Product Description

What is car/bus seat pressure membrane sensor ?


The Car seat sensors is a film type contact sensor, the Car seat sensor's contact points are evenly distributed on the seat's stressed surface, Car seat sensors Generate a trigger signal when the seat receives a pressure from the outside. The Car seat pressure sensors applies to the car seat occupancy perception system, Such as car seat belt alarm sensor system, Taxi automatic meter, car Airbag sensing system and Driver's departure sensing. For example with this Car seat sensor, It can sense whether there are people on the seat or not, Airbags will not open if there is no one. When the driver leaves the seat, the car will automatically return to neutral. People Design car seat sensor shape and contact points' sensitivity According to the car seat's shape, hardness, and skin tightness.


The car seat pressure sensors usually contain four layers, up circuit layer, between adhesive layer, down circuit layer and back adhesive layer. Other accessories are wire cables and connectors.

The Structure and Working Principle of car seat pressure membrane sensor.

Working principle:

When someone is sitting on a car seat, The car seat surface is subjected to a pressure, This pressure makes the upper and lower circuit layers of the seat sensor contact each other, Thus, the circuit loop is turned on conductive to generate a signal to other devices, Showing someone is sitting on the car seat, and, other systems in the car will use this signal to work, For example, the seatbelt warning system will detect if the person on the car seat whether put a seat belt on himself.
