Tactile sensor based on pressure change measurement is simple and cheap solu-tion when magnitude of force is required. The touch sensor works on the princi-ple of pressure change caused by deformation of flexible spherical membrane. The magnitude of the force is converted to an analog signal that is easy to pro-cess. The resulting sensor is cheap, accurate and a simple signal processing sen-sor. The sensor is very sensitive. The sensor is also susceptible to noise from en-vironmental conditions unfortunately. The sensor can be adjusted for different load range by changing parameters of the membrane. Furthermore, the electronics can be placed at a greater distance from the sensor by guiding the medium (air) through rigid pipe, which is preferable especially in applications where there is little space.
