Scientists at Binghamton University – State University of New York (SUNY) have created a biodegradable, paper-based battery that is more efficient than previously possible. For implantable devices, it is important to have batteries that work inside the body and eventually disintegrate. Although this new battery wasn’t directly designed for medical applications, it has potential application in medical implantable devices, where electrically powered devices need to perform limited tasks and they don’t have to be removed after the job is completed.
For years, the scientific community has been excited about the possibility of echo-friendly paper-based batteries as an alternative to regular batteries. The proposed designs, however, were never quite robust enough, they were hard to produce and there were questions about their biodegradability.
This new design solves all of those problems.
Working together in the project were: associate Professor Seokheun “Sean” Choi from the Electrical and Computer Engineering Department and Professor Omowunmi Sadik from the Chemistry Department. Choi designed the paper-based battery, while Sadik made the battery a self-sustaining biobattery.
“There’s been a dramatic increase in electronic waste and this may be an excellent way to start reducing that,” said Choi. “Our hybrid paper battery exhibited a much higher power-to-cost ratio than all previously reported paper-based microbial batteries.”
As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email email@example.com to let us know about your post so we can blog it up here.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
