Miniature Sensor Electronics – embeddable

Measuring the value of capacitive stretch sensors and strain gauges is not trivial due to their unusual electrical characteristics. If your application requires high accuracy measurement of this kind of sensor, this device is an ideal compact and precise converter circuit. Being part of a more sophisticated platform makes application specific solutions simple to develop.

The circuit is designed to convert changes in the sensor’s capacitance, caused by their deformation, into an analogue voltage signal linearly representing these changes.

APPLICATION EXAMPLES

•Portable sensor products

•Smart textiles

•Rubber component monitoring

•Wearable motion capture

(Sports, wellness, rehabilitation)

•Respiration

•Robotics monitoring and control

•Structural health monitoring

Using the circuit can eliminate the need for custom development of a dedicated capacitance measurement circuit for your application, reducing time to market.

The measurement range of the circuit is software configurable. This adds versatility, allowing the circuit to measure all sensors, small and large, whilst optimising the measurement accuracy.
