The aim of the ConText project is to develop a vest with integrated sensors and electronics for constant monitoring of muscle activity. The vest measures muscle activity in order to derive the psychological stress level of a person. The ConText project proposes to develop a sensor technology, which requires no direct contact with the body, and to achieve a high level of integration of the sensors and electronics into textile. The realisation of contactless EMG sensors, textile integration of the sensors and the creation of a textile substrate with conductive wiring for data transmission and power supply will be the important parts of the project. The prototype will be used for dissemination and application development. © 2007 IEEE.
