Description:
Medical Grade Polymer with Carbon-Based Nanoparticles. Homogeneously electrically conductive. When this polymer is compressed, the material's electrical conductivity changes. Using this material in combination with one of our SEN0001 to SEN0030 contact electrode boards, the resistance of the material (which decreases as the material is compressed) can be measured using many different circuits, such as a voltage divider, buffered voltage divider, or a current to voltage converter.

Specifications:
Shape: Round
Diameter: 20mm
Thickness: 0.4mm
Maximum Force Capacity: Up to 10kN/cm^2 before sustaining physical damage, varies based on material size, shape and electrode structure.
Cutting: can be cut using plotters, scissors, knife, or cutting dies. Do not cut using laser or waterjet.
Chemical Stability: Chemically stable.
Durability: >500,000 loading cycles
Operating Temperature Range: -40C to +200C
Maximum Temperature Range: -40C to +250C, for short duration during installation.

Recommended Circuit Wiring:
In combination with a compatible SEN0001 to SEN0030 electrode board. Voltage divider: Electrode with force sensing material on it wired as the top resistor connected to Vcc (for example 3.3V or 5V), and the bottom resistor is a pull-down resistor of 10k ohms to 100k ohms. When the material is uncompressed, its resistance is in the megaohms range. When compressed, its resistance decreases exponentially to the kiloohms range. The circuit node voltage between the resistors can be measured by any microcontroller, using a digital input for simple press detection, or with an analog input using an internal ADC to measure analog voltage and calculate applied force.

Care and Cleaning
NANOCOMP force sensing material is flexible and washable.

Photos / What's Included:
Includes 1x NANOCOMP-CRC-20X20 force sensitive polymer sheet.
Some photos show the force sensitive material with a SEN0024 interdigitated electrode flex PCB for illustrative purposes only, not included, sold separately.
