Every day hundreds of weather balloons are introduced all above the planet, utilizing radiosondes to measure stress, relative humidity, and temperature. The balloons are not environmentally welcoming, even though, in portion since they’re manufactured out of nonrecyclable elements this sort of as latex. Also, there’s a lot of squander.

Soon after a several hrs in the air, a weather conditions balloon bursts and its radiosonde falls to the floor by way of a parachute. Out of the 75,000 radiosondes launched each individual year in the United States, only 20 percent are discovered and returned, in accordance to the National Temperature Provider. The cost of replacing them provides up.


Amon Schumann, a senior at the Robert-Havemann-Gymnasium faculty, in Berlin, has invented eco-welcoming, cost-productive options.

Schumann built a coin-measurement, solar-powered radiosonde that weighs 4.8 grams—far much more compact than present versions, which weigh about 96 g. The weather conditions balloon he created can keep in the air lengthier than classic styles as perfectly.

His Compact Radiosondes on a Wonderful Mission venture was showcased in Might at the Regeneron Global Science and Engineering Good held in Atlanta.

At a unique awards ceremony, Schumann was caught by shock when it was declared that his job obtained the IEEE Presidents’ Scholarship. The award was recognized by the IEEE Basis to accept a deserving college student for a undertaking that demonstrates an understanding of electrical or electronics engineering, laptop or computer science, or other IEEE subject of interest. The scholarship is administered on behalf of IEEE Academic Functions and is payable above four years of undergraduate university study. Schumann also been given a complimentary IEEE pupil membership. Susan K. “Kathy” Land, the 2021 IEEE president, introduced Schumann with this year’s scholarship.

“In comparison to launching 2,000 to 5,000 balloons that keep up for just two to a few several hours, my balloon can continue to be up in the air for 52 days.”

Schumann was determined to enhance radiosondes and temperature balloons all through a check out to a nearby meteorology museum. There he realized that radiosondes have not noticeably altered in the past 100 many years.

Environmentally Friendly

Mainly because of the raise in air pressure at high altitudes, weather conditions balloons burst at about 35 kilometers. To tackle the problem, Schumann applied levels of foil welded alongside one another, in addition a heated Teflon wheel, to build a balloon that is capable to stand up to higher altitudes.

“In comparison to launching 2,000 to 5,000 balloons that continue to be up for just two to three several hours, my balloon can keep up in the air for 52 times, so fewer balloons have to be released,” he suggests.

His radiosonde gives many occasions far more measurement information per working day when compared with classic kinds launched just about every two months. The radiosondes are geared up with a solar-driven battery, which is about 20 grams lighter than a lithium battery.

Schumann also developed an extension module with a digital camera to file further data this sort of as cloud development.

“The digital camera can acquire aerial illustrations or photos of the clouds,” he says, “which enables for a extra exact watch of their development and connections in comparison to a conventional radar program.”

He included GPS to keep track of his radiosonde in true time. The radiosonde’s area is uploaded to his balloon flight tracker, which he hopes will be of use to individuals needing weather data.

The computer software he made allows for the radio weather conditions facts packets to be transmitted in authentic time from his radiosonde to an analysis unit in his property. The data is then despatched to the Citizen Temperature Observer Application, a volunteer-centered network. From there it is forwarded to the Nationwide Oceanic and Atmospheric Administration for achievable use in typical temperature forecasting.

Schumann claims he strategies to review electrical engineering at a technological college in Berlin.

Brain-Laptop or computer Interface

This year’s 2nd-place receiver was Navya Ramakrishnan, a senior at Plano Senior Substantial School, in Texas. Her interface utilizes brain alerts to full house duties these types of as turning on a television.

Ramakrishnan’s brain-computer interface was built for men and women with paralysis and neuromuscular conditions together with amyotrophic lateral sclerosis. She claims her inspiration came from the device Steven Hawking crafted that applied his eye actions to talk.

“That was unquestionably the commencing position, when I considered about a way to have a universal interaction-aid equipment for ALS patients,” Ramakrishnan states. Alternatively of using eye actions, she utilised brain waves measured by an EEG headset to gauge exercise.

She uncovered that a spike in the EEG info, a P300 sign, happens in response to an occasion. Employing a pc keep an eye on, she developed a visible show of generally used household-automation command phrases. The BCI process is related with the home’s circuit, which controls lights, appliances, and extra. The command is executed by way of wi-fi transmission to the portion of the circuit in manage of that undertaking.

When consumers see their wanted command flash on the watch, they count in their head right up until it stops—which triggers a reaction and makes a P300 signal. The BCI method pinpoints which command lit up at the time the signal occurred.

“Let’s say the consumer needs to turn on a light. Just about every time that ‘Light on’ command flashes on the screen I inquire them to depend in their head,” she clarifies. “The counting will crank out that ‘Oh, there’s the light-weight on command,’ reaction, and it will deliver that spike in the EEG data.

“Essentially what my technique does,” she states, “is talk to, ‘Where did people P300 indicators take place?’ Simply because the place they come about suggests the consumer just reacted to the command that flashed on the monitor.”

Ramakrishnan reported she will be attending Harvard this yr to pursue a degree in personal computer science with a concentration in brain, mind, and behavior.

Detecting Leukemia

Adelle Jia Xin Yong, a junior at Westlake Substantial Faculty in Austin, Texas, was awarded third spot for her Smart Leukemia Labs job. Her portable microscope and diagnostic instrument precisely and quickly detects acute lymphoblastic leukemia.

The creation is suitable with smartphones. An attachment magnifies a drop of blood on a .5-millimeter glass slide up to 1,000 situations. An app that takes advantage of item detection, impression recognition, and semantic segmentation identifies abnormal blood cells to diagnose leukemia.

Yong suggests her creation combines her enthusiasm for supporting the community and increasing entry to health and fitness treatment.

“In seventh quality I experienced a pal who sad to say experienced leukemia,” she claims. “As I noticed her go by means of the remedies, I questioned how individuals who did not have accessibility to the technologies she had were being equipped to obtain treatments or even a analysis.”

Yong’s diagnostic software is targeted at these living in underserved regions. It fees about US $28 to make and uses lower-charge products, most of which can be located all around the home, this kind of as a steel pin and a very small plastic tube.

When Yong listened to her identify called at the good, she was shocked, she says.

“ISEF is a truly significant issue,” she says. “I was pleased with my invention, but I didn’t know I would earn a little something. I am just completely thrilled.”

Yong’s father launched her to engineering. In 2020 she taught herself how to code by seeing YouTube films.

She established GStar, a club at her high faculty that is centered on empowering girls in science, know-how, engineering, and math fields.

She states she hopes to show up at health care school and grow to be a doctor. Her objective is to convert her patented prototype into a feasible product or service with the help of brands and labs.
