ACI Material’s Stretchable Electronics (SE) product portfolio offers a complete solution for durable wearable electronics. The products are printed on thermoplastic polyurethane (TPU) films which can be bonded to fabrics. This results in devices that stretch without cracking and maintain excellent electrical properties satisfying the harsh demands of wearable electronics. Early to market stretchable conductors have a narrow scope of application due to limited stretchability without cracking. ACI’s product have a superior combination of electrical performance, resistance to fatigue during cyclic elongation, and excellent recovery. Examples of use in biometric sensors and fixed resistance heaters will be shown.
