Chinese, British Researchers Create Dissolvable Electronics for Medical Implants
Friday, April 29, 2016
Researchers have created a functional dissolvable device component--out of egg, magnesium and tungsten. In early testing, its performance matched that of nondegradable memory resistors, a kind of passive circuit that maintains a relationship between two terminals.
The research was described in a paper in the journal ACS Applied Materials & Interfaces. The components worked under dry la conditions for more than three months. In water, the electrodes and albumin dissolved in two to 10 hours. The remaining chip took about three days to break down, leaving minimal residues.
"This work demonstrates a new way to fabricate biocompatible and dissolvable electronic devices by using cheap, abundant, and 100% natural materials for the forthcoming bioelectronics era as well as for environmental sensors when the Internet-of-things takes off," concluded the paper's authors.
