Cornell University researchers have developed a fiber-optic sensor that, when integrated with low-cost light-emitting diodes (LEDs) and dyes, results in a stretchable skin that senses deformations like pressure, bending, and strain.
The sensor employs a stretchable lightguide for multimodal sensing (SLIMS) featuring transparent and dye-impregnated polyurethane elastomeric cores linked to an LED; each core is mated to a red-green-blue sensor chip to detect geometric changes in the optical path of light.
The dyes function as spatial encoders.
The sensor is coupled with a mathematical model that can separate distinct deformations and pinpoint their precise locations and magnitudes.
The researchers engineered a glove with a SLIMS sensor on each finger, as well as a battery and Bluetooth, that can transmit basic data in order to reconstruct its movements and deformations in real time.
