Abstract: The continuous passive motion exercise system enables human's joints to recover speedily to original functioning after injuries or surgeries, and thus shortens the period of time needed for joint rehabilitation. The present invention provides a force or torque monitoring device attached onto a continuous passive motion exercise mechanism to measure the driving force of the repeated joint flexing and extending motion, so as to evaluate the change of the viscosity and the stiffness of the injured joints through different rehabilitation periods. This monitoring device also monitor degrees of joint muscle's active contraction and thus slows down or stops the repeated motions of exercise mechanisms to improve safety concerns.

Abstract: A micro pressure sensor comprising a glass substrate or a bulk silicon wafer with a rampart protruding from the surface and a plurality of first contacting pads, a thin membrane having a plurality of piezo-resistors, circuit patterns, and a plurality of second contact pads, and conducting lines, wherein the plurality of contact pads are partially exposed to outside. The rampart on the substrate has a cavity formed on the center of the top surface of the rampart. The top surface of the rampart is tightly bonded to the surface of the thin membrane. The piezo-resistors are sealed in the cavity. Preferably, the micro sensor further comprises a plurality of thermo sensors, and a plurality of temperature-controlling elements all enclosed inside the cavity, and additional protective layers formed on the exposure regions of all contact pads.
