A tiny capsule called a Video Capsule Endoscope (VCE) is used to diagnose gastrointestinal illnesses. It is a swallowable capsule with a built-in camera, power source, and light source. The inner lining of the small intestine is photographed by the capsule. This area of the intestine is inaccessible to conventional upper endoscopy and colonoscopy. With the help of this technique, polyps, Crohn's disease, ulcers, and small intestine malignancies can all be identified. This capsule's battery life is its main drawback. The typical battery life is 7-8 hours; however, our minimal digestion takes roughly 12 hours. This paper offers a solution to the issue of the power deficit. We use a wireless means to power the VCE following our method. The VCE's electronic components consume about 100mW of power. Inductive magnetic coupling is used, in which the transmitting circuit generates a magnetic field, and the receiving circuit, located inside the VCE, receives AC power by electromagnetic induction. The AC power is changed into DC power, which provides the VCE with the energy required to complete the process.
