Stretchable fiber-optic sensors use light and color to detect deformation and force – Chemical & Engineering News

A new fiber-optic sensor made from stretchy rubber rather than glass can be integrated into wearable electronics and measure movement. The sensors can also quantify the force of stretching, bending, and pressing movements, so they could be used to gather data for sports medicine and physical therapy.
Most wearable sensing technology detects motion but cant measure the associated forces, says Robert F. Shepherd, an expert in soft materials at Cornell University who led the sensor development team….
