A novel wireless powering solution for active capsule endoscope has been presented in this paper. The self-resonant coil inside the human body is used to receive energy, and the energy is rectified and regulated to generate a stable voltage for charging a button battery, which provides stable power for controlling and driving the system by the low dropout (LDO) regulator fixed in the capsule endoscope...
This paper proposes a novel wireless power supply solution, and designs a power management system-on-chip (SOC) for active capsule endoscope. The SOC consists of a high-efficiency rectifier, two excellent performances low-dropout regulator (LDO) and a rapid battery charger management unit. The self-resonant coil inside the human body is used to receive energy, and the energy is rectified and regulated...
