Wireless charging systems have seen a rapid rise in medical devices, mobile sensing, consumer electronics, electric vehicles, and other applications due to their high operational flexibility. For elderly persons whose wearable health device batteries might run out but who might forget to recharge them, this project offered wireless charging capabilities for wearable heart rate monitor medical devices. Unlike current expensive and difficult to operate project in the market that delivered power wirelessly to implantable biomedical device, this project is a fast charging technology, low cost and easy to operate wireless charging system. The wireless power transmitter works on the basis that it detects the wireless power receiver and, if the latter is within communication range, the transmitter is enabled; otherwise, it is in sleep mode. The LCD screen of the receiver displays the voltage that it is supplied with. The wearable device will receive power when a voltage of 5V is detected. The Arduino Uno was powered by the battery’s 9V supply during project implementation, which also powered the transmitter coil in the transmitter part. The electromagnetic field that was radiated was captured by the receiver coil in the receiver portion, and it was then converted to DC (Direct Current) voltage so that the heart rate monitoring device could be charged. The implemented design worked effectively based on result of performance test obtained.
