This paper proposes a wireless energy transmission system for in vivo robotic capsules via 125 kHz radio frequency inductive coupling. We designed a transmitter with class E power amplifier to provide maximum power with high-efficiency. Through various types of material, this system transmitted up to 350 mW power stably within 5 cm distance.
