Wireless body area network of intelligent motion sensors for computer assisted physical rehabilitation
From Capsil Wiki
Jovanov et al in this proposed a general system architecture and describe a recently developed activity sensor called "ActiS". ActiS is based on a standard wireless sensor platform and a custom sensor board with a one-channel bio amplifier and two accelerometers. As a heart sensor, ActiS can be used to monitor heart activity and position of the upper trunk. The same sensor can be used to monitor position and activity of upper and lower extremities. A wearable system with ActiS sensors would also allow one to assess metabolic rate and cumulative energy expenditure as a valuable parameter in the management of many medical conditions. An early version of the ActiS has been based on a custom developed wireless intelligent sensor and custom wireless protocols in the license-free 900 MHz Scientific and Medical Instruments (ISM) band.
The ActiS sensor was developed specifically for WBAN-based, wearable computer-assisted, rehabilitation applications. ActiS consists of a standard sensor mote platform, Telos, from Moteiv and a custom Intelligent Signal Processing Module – ISPM
An example application of the ActiS sensor as motion sensor on an ankle used to measure angular position and velocity for rehabilitation purposes.
