Low-Cost Sensors and Biological Signals

Many sensors are currently available at prices lower than USD 100 and cover a wide range of biological signals: motion muscle activity heart rate etc. Such low-cost sensors have metrological features allowing them to be used in everyday life and clinical applications where gold-standard material is both too expensive and time-consuming to be used. The selected papers present current applications of low-cost sensors in domains such as physiotherapy rehabilitation and affective technologies. The results cover various aspects of low-cost sensor technology from hardware design to software optimization.
