Development of Low-cost Intelligent Wearable Motion Sensing Device Using Embedded Controller

The importance of wearable devices in nursing care and rehabilitation has been strongly recognized. The purpose of our study is to develop a wearable motion sensor. In our previous study, we had proposed tested a “Skin Displacement Sensor” by using a string type flexible displacement. This “Skin Displacement Sensor” can measure the movement of the human body by measuring the displacement of the skin. In this paper, an inexpensive intelligent wearable motion sensing device that can automatically adjust the offset signal from the skin displacement sensor and amplification factor is proposed and tested. In addition, a wireless communication device is installed into the tested device.
