Multi-capacitor sensor array with integrated temperature measurement

A combined force- and temperature-sensing array includes an array of drive plates, an array of sense plates corresponding the drive plates, and a layer of dielectric material separating the drive and sense plates. A diode with a forward junction voltage is connected between at least one of the drive...

Beschreibung
Zusammenfassung:	A combined force- and temperature-sensing array includes an array of drive plates, an array of sense plates corresponding the drive plates, and a layer of dielectric material separating the drive and sense plates. A diode with a forward junction voltage is connected between at least one of the drive plates and at least one of the sense plates. A multiplexer is operative to select between an electrical pulse or an electrical current for delivery to the at least one drive plate. Circuitry is provided for sensing an applied force resulting from a change in capacitance between the at least one drive plate and the at least one sense plate when the electrical pulse is delivered, and for sensing a temperature resulting from a change in the forward junction voltage of the diode when the current is delivered. The sensor array may be provided as a shoe insert for diabetics with neuropathy.
