Sensor substrates based on biodegradable glass materials

This work explores the feasibility of temporary implantable devices utilizing an inorganic material as the core structural element. A biodegradable glass material was used as the substrate for the devices. A device test structure composed of two thin film elements, an insulating layer and a pair of metal electrodes, was formed on the biodegradable glass substrate. The devices were then subsequently tested for their operation in simulated body fluids. This feasibility study is expected to lead to a variety of useful solid-state sensors and actuators that can be applied to many medical areas that can benefit temporary implantable devices.
