2. Force-sensing resistor - Wikipedia

   en.wikipedia.org/wiki/Force-Sensing_Resistor

   As with all resistive-based sensors, force-sensing resistors require a relatively simple interface and can operate satisfactorily in moderately hostile environments. Compared to other force sensors, the advantages of FSRs are their size (thickness typically less than 0.5 mm), low cost, and good shock resistance. A disadvantage is their low ...

3. Force-sensing capacitor - Wikipedia

   en.wikipedia.org/wiki/Force-sensing_capacitor

   A force-sensing capacitor is a material whose capacitance changes when a force, pressure or mechanical stress is applied. They are also known as "force-sensitive capacitors". They can provide improved sensitivity and repeatability compared to force-sensitive resistors [1] but traditionally required more complicated electroni

4. Force control - Wikipedia

   en.wikipedia.org/wiki/Force_control

   Since force/torque sensors are still relatively expensive (between €4,000 and €15,000) and very sensitive to overloads and disturbances, they - and thus force control - have been reluctantly used in industry. [3] Indirect force measurement or estimation is one solution, allowing force control without costly and disturbance-prone force sensors.

5. Piezoelectric sensor - Wikipedia

   en.wikipedia.org/wiki/Piezoelectric_sensor

   A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo- is Greek for 'press' or 'squeeze'.

6. Force Touch - Wikipedia

   en.wikipedia.org/wiki/Force_Touch

   Force Touch is a haptic pressure-sensing technology developed by Apple Inc. that enables trackpads and touchscreens to sense the amount of force being applied to their surfaces. Software that uses Force Touch can distinguish between various levels of force for user interaction purposes.

7. Four-terminal sensing - Wikipedia

   en.wikipedia.org/wiki/Four-terminal_sensing

   Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
