Abstract: Device for alarming foot weight capable of operating without restricting an individual's movement. The device comprising a power supply, at least one resistive force sensor, signal conditioning means, calibrating means, programming means and alarm generating means. The alarm generating means generates an alarm when the weight applied to the foot force sensor is at, within or above at least one weight limit or weight range.

Abstract: Foot force sensor for measuring compressive force exerted by a foot. The foot force sensor is in the form of an insole made of layers of relatively thin, planar, flexible, resilient, dielectric material. Electrical contact means having first and second poles and electrical leads extending therefrom is interposed between the layers of the insole. An electrically resistive material is also interposed between the layers of the insole but displaced from the electrical contact means. An electrically conductive interconnecting means is connected between the electrical contact means and the electrically resistive material. The electrically conductive interconnecting means has a plurality of electrically isolated conductive paths laterally displaced from one another and extending through it.
