The Flexiforce sensor features a pressure sensitive disc pad on the end of an ultra-thin (0.008 in.) flexible printed circuit ribbon that can be easily integrated into force measurement applications. Note that the flexible ribbon is to accomodate optimal placement of the pressure-sensitive disc; the sensor does not measure force applying curvature to the ribbon itself.
With the Flexiforce Sensor Kit, you can:
- Detect and measure a relative change in force or applied load
- Detect and measure the rate of change in force
- Identify force thresholds and trigger appropriate action
- Detect contact and/or touch
Key Features:
- 25 lbs load capacity
- Versatile small size
- Configurable accuracy
- Easy programming
Application Ideas:
- Touch Pads (i.e. VR Gloves, Joysticks)
- Alarm Systems
- Airbag Force
- Aerospace
- Horn Press
- Robotic Grip Force
- Compression Moldings
This will allow you to demonstrate the resistive nature of the sensor with a resistor/capacitor discharge-time measurement circuit; no correlations to weight are made. The resistance of the FlexiForce sensor is proportional to weight. The sensor included in the kit has a resolution of ≈ 1.6lbs. The active sensing area is a .375" diameter circle at the end of the sensor. The conductive leads are easy to connect to a breadboard or through-hole area. The Flexiforce has an ideal output for A/D conversion - 0 V is no force and 4.2 V is 25 lbs. The RCTIME command may be used with a LOOKUP table or calibration formula to execute some math to make the output useful.
