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
