Tactile sensor with housing

Abstract

The present invention discloses a tactile sensor with a housing having a sensor unit comprising: a first layer with a first electrode, a second layer with a second electrode, a pressure sensitive material separating the first and second electrodes the middle layer. The tactile sensor has a housing in which a sensor unit is arranged. At least the first electrode is made of a conductive thread, and the sensor unit extends substantially in a longitudinal direction defined by the conductive thread. Furthermore, the first and second electrodes and the pressure-sensitive material define an active area of ​​the sensor unit, which is designed such that compression of the pressure-sensitive material in the active area results in a change in the electrical property between the first and second electrodes that can be detected by the evaluation unit. The housing comprises a main body designed to accommodate the sensor unit, a compression body designed to transmit mechanical forces applied thereon to the sensor unit, and a joint designed to couple the housing to the support. The housing with the main body, the compression body and the joint extends in the longitudinal direction and is integrally formed of elastic material.

Description

technical field [0001] The invention relates to a tactile sensor with a housing and a device for closing an opening using such a sensor. The invention also relates to a corresponding housing. Background technique [0002] It is known in building technology to provide anti-trapping devices for automatic doors, gates or windows or for vehicle doors in public passenger transport. Anti-pinch devices prevent obstacles from being pinched at the cutting edge by stopping or reversing risk-inducing movements when an obstacle is detected. [0003] Simple systems achieve anti-trap partially mechanically through feedback or friction couplings. In the case of more complex or convenient systems with automatic closing, the anti-pinch is obtained by determining the drive torque as a function of the window position. If a certain limit value of the drive torque is exceeded, the movement is stopped or the direction of movement is reversed to release the obstacle. In this case, it is necess...

Problems solved by technology

However, light grids and gratings have the disadvantage that in principle only straight edges can be reliably protected

Correspondingly, other optical systems based on image processing for object detection are generally oversized and expensive for use as anti-trap devices
