Pressure Sensing Mat

The flexible and stretchable dielectric silicone sensors (DES) can be excellently integrated into textiles. Sensor size, arrangement and number are freely adjustable and thus make it possible to realize an individual measuring surface with a high spatial resolution.

Special advantages are the softness, low thickness (approx. 2 mm) and high elasticity of the arrangement, which means that even strongly curved surfaces can be covered with sensor arrays.

The measured pressure values are evaluated electronically and can be transmitted wirelessly via Bluetooth.

The flexible and extensible dielectric silicone sensors (DES) can be excellently integrated into textile carriers. By a freely determinable arrangement of many small sensor points it is possible to realize an individual measuring surface with a high spatial resolution. With the help of ASIC electronics, up to 40 measuring points can be recorded simultaneously at a high sampling rate of 50 Hz. The data can be sent wirelessly to a receiver for evaluation. With such a measuring mat it is possible, for example, to record the weight distribution on a seat or on a bed rest. A mobile, rollable scale was developed as a demonstrator, which can also be used to control the device by means of weight distribution.
