Antratek is distributor of force sensors from Tekscan. FlexiForce sensors are, compared to other force sensors, more linear, have less drift, have better rehabilitation, have a wider range and are less sensing area dependent. We have different shapes and sizes in stock with a force range of 1 lb (4,4 N) up to 1000 lbs (4400 N). The resistance of these piezoresistive sensor changes when pressure is applied. An example circuit is available, but we can also supply a FlexiForce Quickstart Board and a complete Force Measurement System.
