摘要

随着虚拟现实(VR)和增强现实(AR)市场的扩大,通过人机交互密切传递运动变得越来越重要。聚氨酯是一种用于各种服装和西装的纤维,具有合适的弹性和拉伸强度。这使得它成为一种可以紧密附着在皮肤上而不会引起不适的材料。然而,由于聚氨酯不是导体,它的缺点是无法检测电信号。在这里,我们合成了聚氨酯磺酸盐(pu),它是一种含有大量磺酸基的亲水改性聚氨酯。该改性聚氨酯与聚(3,4-乙烯二氧噻吩)-聚苯乙烯磺酸酯(PEDOT:PSS)的亲和性通过磺酸基与PSS的分子间相互作用得到改善。最后,将PEDOT:PSS涂覆在pu上,在100 cm2的大面积上制备了弹性应变传感器。该应变传感器根据pu的弹性膨胀引起电阻变化。将自制的应变传感器应用于手指关节和肱二头肌,成功检测到相应的弯曲和膨胀运动。图形抽象

Preparation of polyurethane sulfonate films as a motion sensing substrate with the compliant coating of PEDOT:PSS

With the expansion of the virtual reality (VR) and augmented reality (AR) market, the close transmission of movement through human–machine interaction has become increasingly important. Polyurethane, a fiber used in various clothing and suits, possesses suitable elasticity and tensile strength. This makes it a material that can be closely attached to the skin without causing discomfort. However, since polyurethane is not a conductor, there is a disadvantage that it is impossible to detect electrical signals. Here, we synthesized polyurethane sulfonate (PUS) which is a hydrophilic modified polyurethane containing a high amount of sulfonate groups. This modified polyurethane shows the improved affinity with poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) by intermolecular interaction of sulfonate group and PSS. Finally, an elastic strain sensor was fabricated with PEDOT:PSS coated on PUS over a large area of 100 cm2. This strain sensor induces resistance changes according to the elastic expansion of the PUS. The fabricated strain sensor was applied to finger joints and biceps, successfully detected movements corresponding to bending and expansion.
