pliance Hardware

pliance systems offer the state of the art technology for pressure distribution measurement between soft and curved surfaces.

As in all physical measuring systems, the most important component is the sensor technology. pliance works with capacitive transducers in a matrix configuration. The elasticity of the sensor mats permits conformability to 3-dimensional deformations.

The pressure transducer elements contain high-tech elastomers manufactured by novel. The restoring force, range of force, threshold, hysteresis, temperature effect, frequency response and other characteristics are determined during the manufacturing process. This makes it possible to adapt the sensor characteristic to different measuring needs. The elastic measuring mats are available in various sizes, sensor configurations and pressure ranges.

novel developed an analyzer technology that not only allows individual calibration curves for each sensor, but also individual dynamic amplification control and crosstalk suppression, resulting in very accurate and reproducible pressure values. The pliance analysis can work with a PC via the USB interface. Notebook computers or even a pocket PC can be used for mobile tests.

The pliance analyzers vary from small portable 16x16 channel units to large 112x112 channel units with a wide range of options, such as master-slave synchronization of several systems, dynamic amplification control, synchronization of video systems and analog inputs for accelerometers.
