* Specifications are derived from measurements taken at 1000 grams, and are given as one standard

deviation / mean, unless otherwise noted.

1.

Max Actuation force can be modified in custom sensors.

2.

Force Range can be increased in custom sensors. Interlink Electronics have designed and

manufactured sensors with operating force larger than 50Kg.

3.

Force sensitivity dependent on mechanics, and resolution depends on measurement electronics.

Applications

Detect & qualify press

Sense whether a touch is

accidental or intended by

reading force

Use force for UI feedback

Detect more or less user

force to make a more intuitive

interface

Enhance tool safety

Differentiate a grip from a touch

as a safety lock

Find centroid of force

Use multiple sensors to

determine centroid of force

Detect presence, position, or

motion

Of a person or patient in a bed,

chair, or medical device

Detect liquid blockage

Detect tube or pump occlusion

or blockage by measuring back

pressure

Detect proper tube

positioning
