Flexible Piezoresistive Material

Request Number N080184
Need details

IncWell's partner seeks novel materials displaying piezoresistive properties.



There are materials, such as germanium which is used in the production of semiconductors, exhibit changes in electrical resistance whenever a mechanical strain is applied.


However, these materials tend to be rigid in nature. IncWell's partner seeks materials which can display this piezoresistive behaviour in a flexible form factor.


Key Success Criteria

The successful material will:

  • Be flexible with thickness < 1mm
  • Not be subject to creep and tension relaxtion
  • Withstand the pressure thresholds in geometries (~ 25mm circle / < 1mm thick) in the elastic regime of deformation
  • Exhibit no phase changes between -45°C and 150°C
    • Phase change can be admissible at this given temperature range when/if the electrical  and mechanical properties are stable and homogenous
  • Ideally cost less than $0.01/mm2


Possible Approaches
  • Silicon-based materials
  • Rubber-based materials


Approaches not of interest



Preferred Collaboration types
  • Joint Development
  • Technology Licensing
  • Supply Agreement
  • To Be Negotiated

One of the key success criteria is that the material must be able to withstand the pressure thresholds. What is the expected operating pressure? Additionally, does the material need to show a linear response across the entire range of pressures?

Lastly, are there metrics for the flexibility of the material (e.g. % elongation, hardness, minimum radius of curvature, etc.)?
