Abstract
A deformable differential semiconductor sensor system of pressure and/or compressive displacement is provided. The pressure sensor system includes a deformable and elastic rubber substrate, first and second carbon nanotubes conductive layers, metal free phthalocyanine-carbon nanotubes composite semiconductive layers, first and second terminals on the carbon nanotubes conductive layers and a rubber cover for receiving inputs. The conductive and semiconductive layers of the sensor system are embedded in deformable substrates by using rubbing-in technology.
Claims19
A differential pressure sensor comprising:
- a deformable cover for receiving a plurality of inputs including at least one direct input and at least one side input, wherein the deformable cover is in a cantilevered structure having a supported surface and an unsupported surface, wherein the at least one direct input is applied on the supported surface, and wherein the at least one side input is applied on the unsupported surface;
- a first conductive layer and a second conductive layer made of carbon nanotubes (CNTs);
- at least two terminals configured to measure a differential pressure;
- a semiconductive layer arranged between the first and second conductive layer, wherein the semiconductive layer is a composite of phthalocyanine and CNTs;
- and
- a deformable rubber substrate, wherein the first and second conductive layers and the semiconductive layer are arranged between the deformable cover and the deformable rubber substrate, and wherein the first conductive layer and the semiconductive layer are embedded in a deformable cover facing surface of the deformable rubber substrate.
