Clear, flexible electronic circuit may pave way for implantable devices

Swiss scientists have created a transparent, flexible electronic circuit whose diminutive footprint may one day make it suitable for use in implantable medical devices or environmental sensors. The prototype device is actually small enough and thin enough to fit on the surface of a contact lens or be wrapped around a finger, hair or plant leaf, Smithsonian reports. The circuits are printed on a one-micrometer-thick layer of a substance called parylene. According to Giovanni Salvatore, a researcher at the Swiss Federal Institute of Technology, the circuits could eventually be used in "very conformable and implantable devices which can serve to monitor biometric parameters in the human body."
