Miniaturized electomechanical device

Lesions of certain skin diseases, such as psoriasis and melanoma, present a higher degree of surface stiffness than normal, surrounding tissue.  Knowing this, engineers at Northwestern University and Chinese collaborators) have designed  a miniature electromechanical device that detects different tinsel strengths in soft tissue.  “The device is composed of a piece of soft, strain-sensing sheet with a vibratory actuator that allows it to sense tensile stiffness of the skin. Placed on the skin, the device can measure tissue stiffness from depths of approximately 1 to 8 mm and provide extremely precise real-time evaluations.”     MORE
