WiFi Medicine: Implantable Biosensors That Could E-mail Your Doctor

By Jeremy Jacquot | August 20, 2010 2:00 pm

Silk-based metamaterialHaving already become a ubiquitous part of our mobile-centric daily lives, wireless technologies are now poised to slip inside our bodies. Researchers and companies around the world are designing the next generation of biosensors—implantable microchip-like devices that can monitor a patient’s health and ping doctors on their smartphones or computers if something is amiss. One day, some of these devices could even apply short-term fixes or treat disorders outright.

The major challenge that scientists face is developing a sensor that is both long-lived and biocompatible. The human body is extremely picky about implants, and will quickly reject or react poorly to most materials found in everyday electronics. Even the materials that make peace with the body’s immune system, like those found in pacemakers, are not always ideal. Some require constant maintenance, while others need to be replaced every few days and are inconvenient to install, to say the least.
