Ambient Assisted Living (AAL) systems demand https://www.instapaper.com/p/swisskenya6 is raising. The usage of mattress seat occupancy sensors is crucial for this sort of ubiquitous monitoring techniques. Pressure mats are a first means to solve this characteristic, but a number of environmental dependencies make them weak to be an environment friendly and reliable solution for big volume deployments. Options primarily based on force-to-resistor transducer appears to suggest a too high power consumption to be integrated on wireless sensor nodes. A drive-capacitive transducer based mostly sensor has been proposed, implemented and tested on this paper. This sensor, based on Electro-Mechanical Movies (EMFi) is able to detect drive variations in a quasi-passive way. This detection is used to trigger an lively mechanism to measure the weight by way of the transducer capability. A low-power wireless sensor node prototype including this new sensor has been assembled and tested with a wide range of weights.
