Abstract: This technology is directed to wearable on-skin interface devices comprising a textile structure with components that function to detect environmental inputs and provide outputs as responses. The textile structure is a woven or knitted texture structure with circuitry, sensors, and actuators incorporated into the textile structure for electrical connections between the layers while maintaining a slim form. The wearable on-skin interface devices comprise a microprocessor that receives inputs from the sensors and uses the inputs to initiate response functions from the actuators. Conductive materials may be woven into the textile structure to establish electrical connections between adjoining layers of the interlaced materials to form one or more electrical vertical access structures.

Abstract: A stretchable fiber optic pressure sensor is a sensing device that uses stretchable optical fibers that deform in response to an applied force. A deformation of a fiber causes a decrease in an intensity or alters a duration of the transmitted light due to a bend, crease, or dent in the fiber. The sensor may be configured to determine a pressure or force as applied by an appendage of a user. Multiple sensors may be configured to be in contact with multiple appendages, such as insoles inserted in shoes to determine walking attributes such as a gait, posture, pace, toe-walking, limping, stumbling, foot drop, swaying, or shuffling of a user. The sensor is configurable to transmit data associated with the applied pressure or force to a user's mobile device or computer to monitor or diagnose health issues associated with walking attributes determined through the use of the sensor.
