Bend Sensor
®
Measurement using a Cypress PSoC Microcontroller:
Cypress Semiconductor has a unique microcontroller that has a current DAC. When used in the circuit
above the current source sinks current through the Bend Sensor
®
and generates a voltage across it
which can be measured by the ADC. The current DAC also acts like a variable gain amplifier in the circuit
which can be adjusted to make sure that the voltage across the Bend Sensor
®
is always within the range
of the ADC. The Mux allows each Bend Sensor
®
to be measured separately. The PSoC can eliminate the
need for any external components to measure the Bend Sensor
®
