Sensor Development Using Smart Rubber Technology. The Chest Compression Practice Evaluation System "shinnosukekun".

Abstract

Rubber is widely used in automotive and consumer fields. We are investigating the application to electrostatic capacitive sensors and electrostrictive polymer actuators by making rubber conductive. The conductive rubber sandwiches the dielectric layer (foamed urethane) so that it detects the capacitance change of the layer due to the load stress on the sensor. By using conductive rubber, we have succeeded in developing highly reliable capacitive sensor. We are promoting sensor development that can be used in medical, nursing care and automotive fields. In addition, it can also apply to an electrostrictive polymer actuator by laminating a rubber electrode and a dielectric layer with high insulating property.
