3.0 FSR™ Force Sensing Resistor™ Products
Interlink designs and manufactures a broad array of sensor types. The basic FSR
described above may be made in almost any shape or size and can even made to detect
position in addition to force. All of these products may be combined into arrays:
Single Zone
Single zone sensors can be made in a variety of shapes and sizes. Interlink provides
both custom sensors and a standard catalog of round, square, and strip shaped single
zone parts.
4-Zone Array
4-Zone sensors measure force applied in each of four cardinal directions. These are
typically placed under buttons in keyboards or remote controls in order to create pointing
mice. By measuring force on each zone, smooth 360° control can be accomplished.
Interlink provides both custom sensors and a standard catalog of round and square
shaped 4-zone arrays.
Other Arrays
In addition to 4-zone arrays, any other combination of force sensors can be arrayed on a
common substrate of any shape. One example use is under the keys of a cell phone to
measure force and more naturally fire haptic feedback. Another use is in the medical
field, under mattresses or mats in order to measure patient presence, position, or motion.
Beyond basic FSRs, arrays may include any of the more advanced elements detailed
below.
