Highly Elastic Strain Gage for Low Modulus Materials

NASA Armstrong Flight Research Center, CA, United States

TECHNOLOGY SUMMARY

This strain gage is for highly elastic, low Young’s modulus materials. Conventional foil strain gage technology, including fiber optics, is limited to 20% strains and inherently locally stiffens low modulus materials, reducing strain transfer to sensor. This technology is capable of measuring 125% strains for highly elastic materials.

Primary Application Area: Electronics, Sensors & Communications

Technology Development Status: Prototype

Technology Readiness Level: TRL 4
