Pressure Sensing Mat

The flexible and stretchable dielectric silicone sensors (DES) can be excellently integrated into textile substrates. 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 with 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, e.g. to grasp the weight distribution on a seat or in a doormat. As a demonstrator, a mobile, rollable mat was developed, which can be used for (VR) device control or recording fitness exercises.

As a roll-up scale, it can be used for weight control.

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.

Around 10,000 people die in this country every year as a result of cardiovascular failure, even though they could be saved. In such an emergency situation, only fifteen percent of Germans are confident enough to help the victim with cardiac massage. In the future, a new type of resuscitation mat will make it easier for untrained first responders to revive patients in cardiac arrest. A Fraunhofer research team developed the first-aid tool with integrated sensor technology together with students from the University of Applied Sciences in Munich.
