Abstract
A handheld materials testing device is provided for measuring compressive properties of a material, preferably articular cartilage in vivo. The device is computer-controlled and provides a readout indicative of the desired compressive property, which in the case of bodily tissue, may be indicative of the state of health of the tissue. The device does not require precise perpendicular alignment and is preferably capable of compensating for force applied by the user against the tissue.
