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.
