WaFLES (Water-Filled Laparo-Endoscopic Surgery) is a new operative procedure. However, due to the floating inner organs and tissues, the visibility would be significantly affected. WaFLES-support intra-abdominal micro robots are developed to solve this problem. This paper presents our research efforts into investigating the possibility of ultrasound energy transmission for wireless WaFLES-support intra-abdominal micro robots. A series of experiments were conducted, revealing an appropriate frequency transmission and material for the transmission units in a simulated environment.
