MicroChips has developed prototypes of an implantable microelectromechanical systems (MEMS) devices for healing bones damaged by osteoporosis–replacing 500 daily injections with a single outpatient implant procedure–and for monitoring glucose levels in diabetics.

The technology could also be used with a number of different sensors, providing early warning of heart attacks and strokes, and used to deliver multiple drugs in response to signals from integrated sensors.
