ELECTRONIC SENSOR SYSTEM FOR USE WITH FOOTWEAR

摘要

The disclosed technique relates to an insert for footwear and to a composite orthotic insole comprising said insert, wherein the insert is embedded with a plurality of force (or pressure) sensors, and may be used to provide feedback on important information regarding the wearer's gait biomechanics. The layer of sensors may be used to assist in monitoring the wearer's health via foot pressure tracking. The insole can use a relative large number of sensors, which together provide broad coverage of the human foot impact area.

主权项

1. A flexible, multi-layered insole for footwear, the insole comprising:
a surface layer that binds the insole together and arranged to contact a foot of a user; a pressure-sensitive resistor layer that becomes more conductive as pressure is applied; a sensor layer including a plurality of sensors arranged laterally across the insole, each sensor having a unique identifier; an air gap layer between the pressure-sensitive resistor layer and the sensor layer, the air gap layer configured to collapse at least partially when the insole receives a footfall to thereby cause contact between the pressure-sensitive resistor layer and one or more of the sensors and cause each said one or more of the sensor pads to output a respective signal; and a microcontroller coupled to receive and process the signals received from the sensor pads.
