  • Patent number: 6024575
    Abstract: Insertable insoles of flexible air-injected elastomer material with one or both said insoles containing a lithium-battery power supply (27), a microprocessor with an internal timer, an analog/digital converter, and an actuator (28), connected by at least one wire (29) to a plurality of electronic sensors (12) wrapped around the toes of the foot. The actuator vibrates a plurality of raised nodes (20) on the insole(s) with the speed and intensity of vibrations in either direct or inverse response to the level of stress experienced, as measured by physiological signals such as galvanic skin response. A thin foam lining covers the top surface of the elastomer material and cushions the feet. In addition, a washable, stretchable nylon lining (30) separates the foam from the sole of the bare foot, but a small elastic hole (32) near the toes permits said wire and sensors to extend to the skin of the toes.
