pliance^® – Pressure and load distribution on hard or soft surfaces

pressure measurement- pressure mapping - body pressure mapping | pliance

pliance systems* offer the state of the art technology for pressure distribution measurement between hard, soft and curved surfaces. The systems consist of a flexible and elastic measuring sensor mat, a multi-channel analyser, a calibration device and a software package for PC.

Two kinds of pliance analysers are available: The pliance-xf-16 device scans an array of up to 16*16 sensors, while the pliance-xf-32 device scans larger sensor arrays with up to 32*32 sensors, which is typical for larger seat mats and special high-resolution sensor mats. A master-slave synchronisation of two pliance-xf-32 device allows to operate even more complex configurations, for instance sensor mats to cover bed mattresses.

novel developed an analyser technology that allows not only 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 analyser communicates with the PC via Bluetooth, or alternatively via fibre optic/USB interface. For recordings independently from PC the system can be triggered manually and record data on SD card.

The pliance data acquisition software

The software operates as a Windows application and contains many useful methods of data collection and scientific analysis of dynamic pressure distribution. It also allows continuous data storage in online mode and data handling with a configurable SQL database. The expert can design the parameter configuration to specific needs and exchange data with colleagues via HTML protocol. Different levels of pliance measuring software are available.

The pliance sensors

pliance sensorsare available in various sizes, sensor configurations and pressure ranges. That is why the pliance system is used for various applications e.g. in sports, biomechanics, industry, research, and development.

As in all physical measuring systems the most important part is the sensor technology. pliance works with capacitive transducers in a matrix configuration. The elasticity of the sensor permits perfect conformability to three-dimensional and soft surfaces. 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 are determined during the manufacturing process. This makes it possible to adapt the sensor characteristic to different measuring needs.

trublu calibration device

With the aid of the trublu calibration device, all sensors of the pliance system are individually calibrated. Calibration guarantees accurate and reproducible data and can be checked by the user at any time.
