摘 要：Many emerging medical application systems require the wireless communication functions. Nowadays, wireless medical application for sensing purposes such as the long term electrophysiology signal (ECG, EEG, etc.) monitoring [1], the digestive tract imaging with the wireless endoscope capsule [2], the fetal heart sounds tele-examination [3] and the real-time pressure sensing in artificial joint replacement surgeries [4] have gained many remarkable achievements. Also, the wireless medical applications for intervention purposes such as neural stimulation for cochlear implants [5] and insulin delivery with closed-loop control [6] have preliminarily demonstrated the clinical practice value.
