Highly durable textile pressure sensor based on polyurethane-coated Ni-Ti alloy fiber and its application to real-time sitting posture monitoring |
| 초록 |
A highly durable and washable textile pressure sensor for real-time sitting posture correction was fabricated by weaving polyurethane-coated Ni-Ti alloy fiber which has a shape-memory effect. When pressure is applied to the crossed point of the polyurethane-coated Ni-Ti fibers, a decrease in the thickness of the polyurethane layer results in an increased capacitance signal. Ni-Ti alloy fiber did not experience fatigue failure which made the device highly durable even after repeated deformations and harsh washing process. The real time capacitance changes according to the different sitting postures were successfully demonstrated. |
