About This Product
Students connect a strip into a simple low-voltage circuit, measure its resistance and then stretch it gradually to watch the reading change, before trying a different stretching direction. As a soft, compliant material, it can replace metal and foil in classroom switches and sensors. The Electrolycra Strip is available for supply within India and for export to Bhutan, Guinea, Qatar, Brunei and Malaysia.
Frequently Asked Questions
Q1. How does stretching affect resistance? Pulling the strip increases its resistance, from 5 Ω per 100 mm unstretched to 20 Ω when stretched to 150 mm in one axis. Stretched at 90° to this, it reads 2.5 Ω.
