Abstract: Sensors capable of sensing shear and normal forces and suitable for measuring reaction forces on a body region of an individual, and systems and methods. Such a sensor includes a first plate and multiple second plates that are separated from the first plate by a dielectric material to define multiple capacitor units that are each responsive to normal and shear forces applied to the sensor. Each capacitor unit comprises an individual second plate of the second plates and a portion of the first plate that is superimposed by the individual second plate. The second plates are superimposed on the first plate so that a shear force applied to the sensor causes a first portion of at least one of the second plates to not be superimposed on the first plate while a remaining portion of the second plate remains superimposed on the first plate to define a superimposed area therebetween.

Abstract: Systems and devices for use as lower leg prosthetic devices that include a foot portion having anterior and posterior ends and a first surface having a protrusion that protrudes therefrom adjacent the posterior end of the foot portion, has a semispherical or hemispherical surface with a passage therethrough extending laterally relative to the foot portion. The systems and devices further include a toe portion pivotally coupled to the anterior end of the foot portion, and a plate portion configured to couple to an attachment device and thereby be functionally secured to a user. The plate portion has a recess configured to couple with the protrusion of the foot portion. A cylindrical rod is located within the lateral passage of the protrusion and has ends protruding therefrom on oppositely-disposed of the protrusion. The plate portion is pivotally coupled to the ends of the rod on oppositely-disposed lateral sides of the protrusion.
