Force Sensor using Nano Strain Gauge

Principle of force measurement using Strain Gauges

A force refers to an interaction between two objects. This action may change the position of the object, its speed or its trajectory but especially it may deform it. This deformation will be measured and transformed into an electrical resistance variation by the strain gauges.
The strain gauges are bonded onto a test specimen; the deformation of this object is transmitted to the strain gauge by the glue.
If the applied force stretches the strain gauge its resistance will increase, but if it compresses it, the resistance will decrease.

To measure the variation of the resistance associated to this action, the strain gauges must be installed in the same direction as the applied force.
At rest:

R = nominal Resistance

  Uniaxial tensile test Bending
Compression R
decrease
Traction R
increase

Strength sensor using nano strain gauges

The nano strain gauge allows you to optimize your force sensors:
Their high sensitivity, to measure very small deformations in order to build high precision force sensors.
Their low power consumption (a few micro Watts), to make these force sensors, autonomous sensors.

Examples of applications of force measuring

Force measurement to control the assembly process: fitting, riveting etc.
Force measurement in assembly operations to control production.
Force measurement in some medical equipments (dialyse equipment, syringe pump…)
