Hardware photos. The collage shows photos of a the insole and inlaid pressure sensors (top foam layer missing) b the insole embedded in the orthotic shoe, c a miniature beam load cell and the plastic tendon cups for the tendon sensor, d a subject wearing both of the sensors and e the custom pressure sensor and amplifier unit. The total cost of a pair of insoles was $800 and the total cost of the pair of load cells was $420. Both sensors were easily constructed, assembled, and disassembled without specialty tools
