Hybrid sensor
First Claim
1. A hybrid sensor, comprising:
- a proximity sensor section that includes a first base material having insulating properties and made of an elastomer, a plurality of first front-side electrodes disposed on a front side of the first base material, having conductive properties, and made of an elastomer, a plurality of first back-side electrodes disposed on a back side of the first base material, having conductive properties, and made of an elastomer, and a protective layer disposed on a front side of the plurality of first front-side electrodes, having insulating properties, and made of an elastomer, and that detects approach and coordinates of an object to be detected, based on a change in capacitance between one of the plurality of first front-side electrodes and one of the plurality of first back-side electrodes which is caused by the approach of the object to be detected; and
a load sensor section that is disposed on a back side of the proximity sensor section, and that detects pressing and coordinates of the object to be detected, based on a load that is applied from the object to be detected via the proximity sensor section,whereinthe load sensor section includes a second base material having insulating properties and made of an elastomer, a plurality of second front-side electrodes disposed on a front side of the second base material, having conductive properties, and made of an elastomer, and a plurality of second back-side electrodes disposed on a back side of the second base material, having conductive properties, and made of an elastomer, and detects the pressing and the coordinates of the object to be detected, based on an increase in capacitance between one of the plurality of second front-side electrodes and one of the plurality of second back-side electrodes which is caused as an interelectrode distance between the one of the plurality of second front-side electrodes and the one of the plurality of second back-side electrodes is decreased by the load.

Abstract
A hybrid sensor includes a proximity sensor section and a load sensor section. The proximity sensor section includes a first base material, a plurality of first front-side electrodes, a plurality of first back-side electrodes, and a protective layer. Each of these members is made of an elastomer. The proximity sensor section detects the approach and coordinates of an object to be detected, based on a change in capacitance between the first front-side electrode and the first back-side electrode which is caused by the approach of the object to be detected. The load sensor section detects pressing and coordinates of the object to be detected, based on a load that is applied from the object to be detected via the proximity sensor section.
