Micro robot positioning based on magnetic field detection in bio-sensor networks

Minimally invasive medical care by the aid of ICT (Information Communication Technology) has been paid a lot of attention. Micro robots within the bio-sensor network have been utilized without heavy patient burden. In order to control the micro robots properly, it is important to obtain the accurate position information. This paper provides an effective positioning method based on detection of small magnetic field generated from a micro robot. The proposed method can achieve the accurate positioning with low cost and simple procedure.
