We are looking for piezoresistive materials with flexibility, that can be produced 1mm thick and be flexible at that thickness.
The piezoelectric effect is a change in electrical resistivity of a material when mechanical strain is applied. Materials that exhibit the piezoelectric effect while being flexible would open them up to a number of new applications.
- Cost < USD 0.01 / mm2
- Material should not be subject to creep and tension relaxation at the given pressure thresholds.
- Ability to withstand the pressure thresholds in geometries ~ 25mm circle / < 1mm thick in the elastic regime of deformation.
- No Phase change in ranges between -45C and 150C.
Possible solution areas:
- Silicon-based materials
- Rubber-based materials
- Technology from the semiconductor industry
