Capacitive sensors are used mainly to detect proximity, usually that of people. The operating principle is that the capacitance of the capacitor varies as material comes between the two plates of the capacitor, and you can determine the presence of something via the measurement of the capacitance.

∙ 12y agoA Transducer is a device used to change a mechanical property to an electrical one. Or vice versa.
Common transducers in everyday use would be a microphone and a loudspeaker. They change movement of air to an electrical signal.
Transducers are also used in weighing scales, where a bending moment caused by the weight, is changed to an electrical signal to run the display or other control devices.

What is capacitive transducer?
It is device that will sense the environment in a form of capacitor changes. Usually an oscillator will sense this change and change frequency accordingly
What is the purpose of a pressure transducer?
A pressure transducer measures pressure, specifically that of gases or liquids. Such pressure sensors are used in the measurement and control of thousands of everyday applications. A pressure transducer is just that; a transducer - it generates a signal due to the pressure imposed.
Is iPhone Capacitive or resistive touch screen?
Resistive touchscreens are better if you do not wish to use a stylus. When a stylus is used, capacitive touchscreens respond better. The decision on which is better comes from the applications being used and the preferences of the user.
