Design a compact wireless IoT gait monitor wearable sensory system

The study of human gait analysis is an important endeavor for years, since there are numerous sectors for patients with walking difficulties, such as stroke, sports, and medical rehabilitation. However, such research necessitates the use of equipment that can precisely quantify the movement of body parts. This paper shows a guideline scheme to develop a compact wireless internet of things (IoT) board, starting from embedded system design to kinematic data collection. This work aim is to create an acquisition IoT board that can measure and gather the knee, hip and ankle angles of a person walking normally as well as a patient walking with certain diseases. An enclosure designed to host the board and its associated battery form a wearable unite which it is able to attach to human lower limbs. The electronic board design to establish an inner communication between a high-fidelity inertial measurement unite (IMU) and microcontroller, and an outer communication between microcontroller and radio frequency (RF) module. The board design considers a bidirectional radio communication, though multiple boards are able to share, exchange, and pass IMU data to a personal computer as well.
