There is a need in the market for smart wheelchairs that measure activity data for wheelchair users. This proposal presents a low-power, wireless sensing system that records data of the environment, movement, and fall detection. It is powered by RF energy harvesting, involving an antenna receiving electromagnetic waves from a transmitter and converting them into DC voltage. This device includes a gyroscope and triple axis accelerometer to record motion data and is powered by a battery during the day for at least 8 hours, as tested by the team. The battery is recharged wirelessly at night when the wheelchair is at a docking station. This proof of concept was implemented successfully and met all the requirements of the project.
