Looking for a wearable sensor for your smart textile product? No other strain gauge is as accurate, low cost, or predictable as our sensors. This dev kit includes:
- [ Silicone Ink ] – 2 oz. container of strain gauge screen printing sensor ink*
- [ Catalyst ] – 1 ml syringe of catalyst (15 minute pot life after catalyst is added)
- [ Printing Mask ] – Aluminum mask for DIY printing, no rig needed, just a knife or small spatula
*makes 50 sensors
- [ High Deflection ] – Up to 100% Strain (depending on strain capability of fabric). Our stretch sensors perform best with a Poly/Spandex mix which will strain to 60%. High deflection strain gauges are great for creating wearable products that can measure pressure, strain, and general deformation.
- [ Piezo Resistive ] – Resistance decreases with positive or negative strain. These Strain gauge stretch sensors drop resistance when strained. Excellent for tracking/measuring joint angle and bio-mechanical strain.
- [ Low Power Consumption ] 3.3V or Higher Battery required. Regular strain gauge sensors exhibit Piezo electric properties (increasing resistance when strained). Perfect for DIY wearable tech product prototyping. Starts at ≈4MΩ resistance and ends at ≈100kΩ
- [ Low cost ] Our Strain gauge sensor kits will make between 10 and 50 wearable sensors depending on size and thickness. Other high deformation strain gauges can cost hundreds of dollars per sensor and usually require some alternative attachment method like gluing or sewing.
- [ Negligible Hysteresis ] – This strain gauge will drop several orders of magnitude in resistance. Full sensor functionality is recovered after each strain. Depending on the wearable technology application (high heat or unique substrate), these sensors may change initial resistance over time.
Product developers have used our wearable sensor strain gauge technology to create products related to health and fitness, lifestyle enhancement, and enhanced gaming experience. You can find one study related to the sensors here. >>> Wearable Sensor Posture Case Study
