Abstract

An implantable device contains a drug or biosensing compound, protected from the external environment within a human body by several barriers which are broken upon activation of the device through electrothermal, chemical, and mechanical processes. The device allows accurate and repeated dosing within a human body, thus reducing the number of implantation procedures required. This device extends the lifetime of a biosensor, reducing the number of implantation procedures required.
