A portable apparatus which measures the force-displacement or elastic characteristics of skin in vivo has been constructed. A displacement transducer between two arms measures the extension of the skin as the arms are driven apart by means of a lead screw, and the force exerted on the skin is measured by means of two electrical resistance strain gauges attached at a reduced section on each of the arms. The apparatus was designed for compactness and lightness to enable it to be hand held. Illustrative results obtained on patients during and after courses of radiotherapy are presented.
已构建出一种便携式仪器，用于在活体中测量皮肤的力-位移或弹性特征。两个臂之间的位移传感器在臂通过丝杠驱动分开时测量皮肤的伸展，而施加在皮肤上的力通过附着在每个臂的缩窄部分上的两个电阻应变仪进行测量。该仪器设计得紧凑轻便，以便能够手持。文中给出了在放疗疗程期间及之后在患者身上获得的说明性结果。
