Medical sensors of the BASUMA body sensor network

The BASUMA (Body Area System for Ubiquitous Multimedia Applications) body sensor network will consist of several wearable or handheld wireless medical sensors and a PDA like base station. The sensors, designed in a way to minimize disturbance of the patient's everyday life, will record important diagnostic parameters which are analysed on the base station. This will allow a continuous monitoring of the patient's state of health outside the hospital. Sensors were developed for the measurement of electrocardiograms (ECGs), air and blood content of the thorax (thoracic impedance), body temperature, breathing rate and cough control, blood pressure, pulse rate, oxygen saturation, lung functions, reactive oxygen species (ROS) (exhaled H2O2), and lactate in breath condensate.
