Abstract
We have been developing a system for the measurement of human skin elasticity by applying a pipette aspiration method. In this study, we have integrated the system to develop a portable device. We reduced the number and the volume of the parts by utilizing a compact laser displacement meter, an electronic vacuum regulator, and a pressure transducer with an amplifier, and successfully packed the whole system except a computer in a box of W250×H150×D210mm. By using this device with a notebook PC, we measured the elastic modulus of human skin to find that it reduced with corny layer removal. It can be said that the device is not only portable but also sensitive enough for the measurement of subtle changes in the corny layer.
