Laser-Printed "Papertronic" Circuits Deliver Environmentally-Friendly, Biodegradable Electronics
Researchers from the State University of New York at Binghamton's bioelectronics and microsystems laboratory have come up with a way to turn parchment paper into "papertronic" circuits — by drawing on them with a laser.
"My long-term vision has always been to create a complete, self-powered, disposable electronic system on paper," explains project lead and corresponding author Seokheun Choi of the team's work. "We started with the power source — the biobattery. Then we moved to sensors. The missing piece was the circuit itself: the resistors, capacitors, and interconnects that tie everything together. Imagine a bandage that monitors a wound for infection and wirelessly alerts your phone — and when you are done with it, you throw it in your compost bin. Or a shipping label that tracks temperature and humidity throughout a supply chain, then biodegrades in a landfill. That is where we are heading."
