Northwestern University Invents The Smallest-Ever Electronic Flying Microchip

Published

on

It’s a bird, it’s a plane, no, it’s Ant-Man?

Ant-man has come alive in the form of a winged microchip. The engineers from Northwestern University have created the smallest man-made flying structure through a “winged microchip.” 

The theoretical work was led by experts in bioelectronics Kimberley Querrey and Louis Simpson, Yonggang Huang, and Jan and Marcia Achenbach. These professional engineers built the winged microchip from the concept of a maple leaf’s seed spin. 

Nature has a means of letting living organisms survive through conventional methods, including various plants. Maple leaves spin through the air and land on the surface. When the maple leaves’ seeds disperse, they are widely distributed, allowing sedentary plants to propagate over a vast area. 

The Northwestern University engineers thought about creating a winged microchip to monitor the environment, track diseases, survey population, and more. This is the primary goal of the smallest-ever flying structure called the “microflier.” 

These microfliers has small-scale electronic systems such as power sources, sensors, antennas, and memory data. But what makes this winged microchip interesting is its size, which is the size of a grain of sand. The size is even smaller than a regular-sized ant, making it the smallest man-made electronic flying structure in history. 

How it works

The engineers from Northwestern University created a fully functional microchip that flies without an engine or motor. The technology is based on how maple leaf seeds disperse through the air. On the other hand, the winged microchip has propellers that fly like a helicopter. And this is all thanks to the sophisticated aerodynamics designed in nature to let various plants survive.

John A. Rogers, a biomedical engineer professor from Northwestern University, said, “We were able to do that using ideas inspired by the biological world. Over the course of billions of years, nature has designed seeds with very sophisticated aerodynamics. We borrowed those design concepts, adapted them and applied them to electronic circuit platforms.”

Rogers and an entire team of engineers have already experimented with various microfliers. One microflier was created with three wings about the size of an ant. This microflier has an angle similar to that of a tristellateia seed. The team conducted full-scale computational modeling to perfect the microflier to allow air flows and mimic the seed’s natural and controlled rotation. 

What the microflier lacks in size, it makes up for in the incredible miniaturized electronic solutions. Northwestern University engineers claim it comprises of two parts: The wings and the millimeter-sized electronic elements. Once the microflier flies through the air, the wings function as a stabilizer that allows the winged microchip to create a slow, rotational motion. Furthermore, the weight of the winged microchip is mainly distributed in the center to prevent the microflier from losing control, allowing it to come crashing and tumbling to the ground. 

Inspiration from pop-up books

Another idea that led Rogers’ team to create small-scale flying microchips is due to inspiration from children’s pop-up books. They fabricated precursors in flat, planar geometries. They then integrated these precursors into a stretched rubber substrate. When the rubber substrate is calm, a controlled buckling process causes the wings to pop into precise 3D forms — just like how a children’s pop-up book works. 

Rogers and his team are still in the works of perfecting the winged microchip and are also innovating ways to monitor the environment better. The team even included pH sensors into one of these devices to monitor water quality as well as to gauge sun exposure at various wavelengths.

8 Popular Mobile Payment Systems

Published

on

Offering customers multiple payment solutions is another way to make them choose you over your competitors. Since the world has started this online shift to everything, people prefer convenience via mobile phones. Mobile payment solutions make shopping and paying effortless. If you’re wondering what online payment systems you can offer, we’ve listed the top mobile payment options in this article.

What is a Mobile Payment Solution?

mta metrocards

A mobile payment solution is a payment system people use on their mobile phones. They use smartphones or other cellular phones to pay for products or services. It’s a more convenient, efficient, and faster payment solution since you no longer have to bring cash or change customers’ payments. This type of payment option also means customers pay directly to your account, allowing you to transfer the funds to your bank if the app permits. 

These mobile phones will require the corresponding app or software to enable mobile payment solutions. Some are also done via SMS, depending on the network. Some apps also require users to connect their credit or debit card so people can use the app to pay, and the funds are deducted from the credit card. These apps are called “peer-to-peer” mobile payment apps. 

What are the 5 Types of Mobile Payment Systems?

Business owners can choose from five payment options. While each solution is unique, all alternatives offer a convenient way of transferring money from end to end. 

1. SMS payments

SMS payments refer to payments made through your local cellular network to another. This means a user transfers money by sending it through another person’s number. In most cases, this is only used locally since most can’t transfer from one mobile number to an international mobile number.

2. Mobile wallet

This is another common form of mobile payment. To make a mobile payment, apps like Samsung Pay, Apple Pay, or Google Pay must be installed on portable gadgets like tablets, smartphones, smartwatches, or computers. Most of these apps are linked to credit cards, debit cards, or bank accounts.

3. Mobile peer-to-peer

A mobile peer-to-peer payment system is another efficient solution if you cater to global customers. Some examples are PayPal, CashApp, and Venmo, and most of these accept all business retailers, big or small. 

4. Mobile eCommerce

Mobile eCommerce is also the most commonly used online payment system. This is when a user makes a transaction online from a browser or a seller’s app or webpage and completes the transaction by inputting their credit card details. Users who pay from a mobile wallet or accelerated checkout systems like Shop Pay are also under the umbrella of mobile eCommerce. 

5. Mobile POS (Point of sale)

This payment type refers to paying for products or services using your credit card by swiping it on a terminal or chip reader. You can also use your mobile phone by tapping it on the terminal via QR codes. 

Benefits of Mobile Payments

Most businesses accept mobile payments nowadays due to their security and convenience. While paying cash offers a more secure transaction since you only have to hand the cash to the cashier, online app payments are equipped with robust security measures. On top of that, here are some benefits of mobile payment solutions:

  • Security: Mobile payments require authentication to proceed. This can be done via passcodes, OTPs, fingerprints, or facial recognition. 
  • Speed: Mobile payments can be made in the blink of an eye, making mobile checkout or online shopping easier.
  • Convenience: Customers prefer mobile payments because they no longer have to bring cash or find the nearest ATM to withdraw. All they need is connectivity and their portable gadgets. 
  • Popular: Your business shouldn’t lag behind competitors. It’s no surprise that more and more brands are expanding their online payment systems. Mobile payments are beneficial, especially if your audience is younger. 

8 Top Mobile Payment Systems

While tech companies exhibited their hiring spree during the pandemic to meet online demand, this year leans toward workforce reduction. Most tech juggernauts are looking at AI initiatives for some work processes. This begs the question—are tech experts’ skills in danger of being replaced by faster and more cost-efficient AI tools and platforms? Even the tech tycoon Google continues to lay off thousands of employees. And while tech experts and professionals enjoy Google’s office amenities, these tech layoffs make them ponder: How long will this enjoyment last? Here are some of the top tech company layoffs in 2024. 

1. Dell

Dell Technologies, a computer manufacturer, has laid off about 12,500 employees, constituting 10 percent of the company’s workforce. The company claims it’s part of a “sales and marketing reorganization” that will center on AI services. But this isn’t the first time the company has had a significant layoff. They also cut off about 6,000 workers last February 2023. This restructuring intends to streamline operations and processes, boosting efficiency. This way, the brand can evolve and adapt to a changing and growing market. 

Research Chief Analyst Dave Vellante said, “It’s unlikely the number is that high because that would typically trigger an SEC filing.”

2. Intel

Intel

Intel embarked on a cost-saving plan, a good move for the company in 2025. However, this will mean job losses for 15 percent of its workforce. Laying off about 15,000 employees will save the company $10 billion in 2025. While it’s the estimated number, it may go up to 19,000 out of Intel’s 125,000 employees. The company representatives said it would restructure to stop “non-essential work.” Although the company hit product milestones in Q2 this year, they are still down in the mouth over the loss of $1.6 billion by the end of Q2. 

Representatives said they will “reduce layers, eliminate overlapping areas of responsibility, stop non-essential work.”

3. Qualcomm

Qualcomm

Qualcomm, a company that manufactures software, semiconductors, and other services that pertain to wireless technology, plans to lay off 1,258 employees by December of this year. These employees will mostly be in their Santa Clar and San Diego branches. The company will cut off positions like analysts, software developers, engineers, legal, finance, and human resources. Qualcomm had a 23 percent drop in revenue and a 52 percent drop in net income during Q2 this year.

Palkhiwala said, “Until we see sustained signs of improving fundamentals, our operating framework does not assume an immediate recovery.”

4. Jam City

Jam City is a video game developer and publisher also in for the 2024 tech layoffs. The company has reported to cut 85 employees. And while this number isn’t as shocking as the others on this list, it constitutes 10 percent of their workforce. This is also the second time the game developer laid off its employees, with its first in 2022, letting go of 17 percent of its workforce. Jam City is the genius behind games such as Disney Emoji Blitz, Jurassic World Alive, and DC Heroes and Villains. Some gaming analysts predict an upward trend for this niche in 2024. 

However, Jam City CEO said, “While we have seen moderate improvements in some areas, the overall upward trend has not materialised as expected.”

5. Microsoft

Microsoft also swooped another round of layoffs in multiple departments from various locations. Although the company didn’t disclose the exact number of layoffs, these employees included roles in program and product management. The company confirms this is part of the “regular organizational adjustments” to focus on strategic growth areas. This isn’t the first time the tech company has done a significant layoff. They also cut off around 2,000 employees in January 2024, particularly in the gaming departments, HoloLens, and Azure Cloud divisions.

A Microsoft representative stated, Organizational and workforce adjustments are a necessary and regular part of managing our business.” 

6. EBay

The online shopping brand eBay is also joining the layoffs this year. EBay is cutting off around a thousand employees, accounting for nine percent of its full-time workforce. Jamie Iannone, eBay CEO, announced these changes, stating that the brand is prioritizing more sustainable long-term growth. He said that the number of employees and expenses outpaced the company’s growth. He also noted that employees were encouraged to work from home, so they have the needed space during this challenging period.

CEO and President Jamie Iannone said, “We have to say goodbye to people who have made so many important contributions to the eBay community and culture, and this isn’t easy.”

7. Twitch

Another popular live-streaming platform, Twitch, joins the tech layoffs bandwagon. Amazon’s Twitch cuts 35 percent of its employees, resulting in hundreds of employees scrambling to find job replacements. Twitch CEO Dan Clancy announced that it would have to cut off over 500 people across all departments and claims this is for sustainability in business operations. Although Twitch earns from multiple revenues, such as ads and subscriptions, it’s reported that the company is still unprofitable for nine years. 

Clancy stated, “Unfortunately, we still have work to do to rightsize our company, and I regret having to share that we are taking the painful step of reducing our headcount by just over 500 people across Twitch.”
