Flexible Electronics: Biocompatible Collagen Films as Substrates for Flexible Implantable Electronics (Adv. Electron. Mater. 9/2015)

Collagen is an important component of the extracellular matrix. In article number 1500154, Slobodan Dimitrijevich, Majid Minary-Jolandan, and co-workers demonstrate its use as a substrate for implantable flexible electronics. Scanning electron microscopy (SEM) imaging shows collagen molecules forming a transparent film onto which gold metal is deposited using electron-beam deposition to make flexible conductive metal patterns for resistors, strain/temperature sensors, and antennas that can wirelessly power light-emitting diodes (LEDs).
