ABSTRACT:
A new class of electronic devices: small, robust and high performance, yet also biocompatible and capable of dissolving completely in water – or in bodily fluids. Biodegradable electronics.These are electronic circuits and devices with a limited lifetime owing to their tendency to biodegrade. Such devices are proposed to represent useful medical implants. This idea was expanded using paper-based substrates. Silk coatings could underpin an electronic device because it melts away when the device is no longer needed. One test device, a heating circuit powered by beaming radio waves at it, was implanted under the skin of a rat with a wound. After the wound had healed, the implant simply melts away. ―The US military research agency
DARPA funded research on building a tiny dissolving camera with this silk coating for use as a disposable spy camera.‖
KEYWORDS
Biodegradable Electronics, Transient Electronics,
Electronics, Medical Implants, Consumer Device.
Organic
I.INTRODUCTION
The current era is encountering an emergence of new technologies and devices every single day. A team of U.S. scientists says it has developed a class of biodegradable electronics technology that could be utilized for a wide range of products — from consumer devices to medical implants — and that ultimately would dissolve completely, leaving no environmental impacts. Drawing on techniques that enable the production of systems using ultrathin sheets of silicon that dissolve in liquids, the so-called ―transient electronics‖[1] [2] technology has been used experimentally to make transistors, diodes, temperature sensors, and solar cells that degrade completely in even tiny amounts of water, the researchers say. The devices are
