碩士 === 逢甲大學 === 通訊工程所 === 93 === The e-medical clothing integrates physiological signal sensors, a wireless data transmission module, an analyzing software on PDA or PC, and a power supply module on a specially designed clothing platform which make it a very power medical monitoring equipment. The wireless data transmission module uses radio frequency technology, in our case the Bluetooth technology, to improve the convenience of patients who need their physiological signals monitored on a regular and long term bases. Patients can move freely inside the coverage area of Bluetooth systems without any constraint where medical personnel can effectively retrieve real-time physiological data with no interference to patients. In this thesis, we will describe how to transmit physiological data on Bluetooth modules and use differential encoding techniques to compress the data before transmission to reduce the power consumption of transmissions and in turn prolong battery lifespan on e-medical clothings.
