Body pressure mapping on bed and mattresses

Bed mattress body pressure mapping - body pressure measurement | pliance by novel.de

large size bed rest sensor mat

novel  has developed a large size bed rest sensor mat that covers the full area of a mattress. The mat is highly elastic and conforms perfectly to the surface of a mattress under body load. As with all novel systems the sensors are calibrated accurately to the pressure range obtained during body contact.

Superficial pliance pressure distribution mats allow us to get measurements in soft and bended surfaces, adapting to the specific surface. The system consists of a flexible and elastic mat, an analyzer of multiple signals, a calibrator device and a measurement and analysis software of the pressure data.

As in all physical measuring systems the most important part is the sensor technology. As all novel systems the pliance system is also based on calibrated, accurate, and reliable capacitive sensors. The individual sensor elements are elastic and arranged in a matrix which conforms well to three-dimensional shapes.

The pressure transducing elements contain high-tech elastomers manufactured by novel. Restoring force, range of force, threshold, hysteresis, temperature effect, frequency response, and other characteristics such as elasticity are determined during the manufacturing process. This makes it possible to adapt the sensor characteristic to different measuring needs.
