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.

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 the first front-side electrode and the first back-side electrode 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.
