An apparatus for measuring normal and shear stress at a surface. The apparatus includes a substrate; and a plurality of sensing units on the substrate. Each sensing unit includes a mechanical transducer having a receiving surface and a sensing surface; and a plurality of normal force sensors between the sensing surface and the substrate.

A thermochromic fabric utilizing cholesteric liquid crystals includes a fabric material or garment formed therefrom. The liquid crystal material is patterned with a plurality of different liquid crystal formulations, whereby each formulation has high thermal sensitivity over a narrow temperature range. As a result, the aggregate pattern of liquid crystal material formed on the thermochromic fabric allows the thermochromic fabric to have high thermal sensitivity over a broad temperature range. As such, the fabric or garment may be worn on specific body parts of a patient, such as his or her feet, to assist in making a medical diagnosis.
