How to create an application-optimized thin force sensor. How the sensor was integrated with a standard RFID IC. The various tests run for accuracy and range under different scenarios. Some ...

This video explores four types of contact force: tension, normal contact force, friction and air resistance. Contact forces are forces that can only act when objects are touching each other.
