“…ICPTs scalability between low and high power devices and high potential makes it the oldest and most applied biomedical application for WPT [59], [60]. All near field coupled inductive coils are ICPT because when two inductive coils are aligned and come together, they become magnetically coupled [61]. The electrical energy from the transmitting coil (primary coil) will be transferred to the receiving coil (secondary coil) due to the magnetic field between the primary coil and the secondary coil [62].…”

Real-time pressure monitoring of organs is helpful in habitually tracking a patient's health and assessing the optimal time for medical intervention. Conventional pressure sensors rely on capacitive coupling but trade sensitivity, accuracy, and shelf life for scalability. This project investigates the concept of a novel inductive pressure sensor with aluminum/copper integrated silicon coils, silicon-dioxide insulation, and a silicon base. ANSYS Electronic was used to design and simulate the functionality of the pressure sensor by using displacement of the primary coil to relate pressure applied to the device. The design simulations showed a lower result compared to the expected values, largely due to the simulation applying other variables resulting in more accurate values. The high resistance is a factor that affected the performance of the designs and finding a way to reduce the resistance would be the next step in optimizing the inductive LC coil.
