Practical aspects in surface biopotential electrode placement for smart clothing: A simulation study

In addition to physiological aspects, placement of surface biopotential electrodes for smart clothing should consider practical aspects due to their dynamic application environment. This study is aimed at finding the best places to put the electrode on areas where the measurement is practically reliable. Calculation was performed by using three practical aspects: 1) skin-shirt gap; 2) shirt movement, and 4) regional sweat rate. We employed 3DS Max software to simulate shirt behavior. The simulation result showed that generally practical satisfaction degrees are higher in the posterior. The quantitative approach may help smart clothing designers to choose the locations to place electrodes

Wireless medical interface using zigbee and bluetooth technology

Since years, the using of telemedicine has increased although there are some technical issues related to standard and quality. In order to improve the telemedicine quality of service, a robust wireless connection between medical devices and telecommunication network is required. Unfortunately, many medical devices were developed without possibility to connect with telecommunication infrastructure. Due to this condition, a wireless medical interface has been developed. The interface has been implemented based on the advantages of ZigBee and Bluetooth technology. A new protocol has also been developed to enable robust communication between medical devices and telecommunication infrastructure. The interface has been tested to transfer the medical data from vital sign medical devices to a data processing system through wireless network. Measurement result shows that the interface is able to be used in transferring medical data from multi medical devices within range of 10 m with some interference sources
