Are ultrasonic , touch, colour sensors type of tactile sensor? I have been told not to use tactile sensor in my project. Can anyone name few sensors that are tactile and others which are non-tactile?
but slide shows ultrasonic is tactile sensor.jedishrfu said:PIR, light sensors, acoustical ie ultrasonic aren't tactile.
Here's a description of tactile sensors:

and with more detail:

and a nice slide show:

There are several types of tactile sensors, including resistive, capacitive, piezoelectric, optical, and magnetic sensors. Each type has its own unique way of detecting and measuring tactile information.
A resistive tactile sensor works by using two conductive layers separated by a compressible material. When pressure is applied to the sensor, the distance between the two layers decreases, causing a change in resistance which can be measured and converted into tactile information.
Capacitive tactile sensors work by measuring changes in capacitance, which is the ability of a material to store an electric charge. When pressure is applied to the sensor, the distance between two conductive layers changes, causing a change in capacitance which can be measured and converted into tactile information.
Piezoelectric tactile sensors have the ability to generate an electric charge when pressure is applied to them. This allows for a quick and accurate detection of tactile information, making them ideal for applications such as touch screens and robotics.
Optical tactile sensors use light to detect changes in pressure or contact. They work by measuring the amount of light that is reflected or absorbed when pressure is applied to the sensor. This makes them less invasive and more precise compared to other types of tactile sensors.
