3.0 FSR® Force Sensing Resistor® Products
Interlink designs and manufactures a broad array of sensor types. The basic FSR
described in Figure 1 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 sensor
arrays.
Single Zone FSR 400 Series
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. A Hardware Development Kit is available.
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 a
pointing mouse. 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. A Hardware Development Kit is available.
Other Custom 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.
