Force touch sensors have received a great deal of attention for various applications owing to their versatile ability to detect touch and pressure. To demonstrate high‐performance force touch sensors, numerous studies have been performed, focusing on high sensitivity, transparency, and mechanical durability against bending. However, it is still challenging to apply force touch sensors in flexible applications, because their sensing performance is subject to change and degraded by induced mechanical stress and deformation when the device is bent. Here, a high‐performance and transparent nanoforce touch sensor with bending‐insensitivity is reported. This is achieved by developing a thin, flexible, and transparent hierarchical nanocomposite film, which is composed of a nanostructured plastic base, coplanar electrodes, and a dielectric polymer layer with silver nanoparticles. The fabrication process is simple that high manufacturing repeatability, uniformity, and reliability are achieved on a large‐area (8 in.) scale. The fabricated device shows a pressure sensitivity of 0.036 kPa⁻¹ with high transparency (83%) in a pressure range up to 3 kPa. In particular, its thin thickness (45 µm) and the coplanar electrode enable to achieve excellent insensitivity to the bending with a radius of curvature of 4 mm more than 10 000 times.

工业级，弯曲不灵敏的透明纳米力触摸传感器，通过在多层纳米复合薄膜中增强的渗透作用来实现

强制触摸传感器由于具有检测触摸和压力的通用能力，因此在各种应用中引起了广泛的关注。为了演示高性能的力触摸传感器，已经进行了许多研究，重点是高灵敏度，透明性和抗弯曲的机械耐久性。然而，在柔性应用中应用力触摸传感器仍然具有挑战性，因为当设备弯曲时，其感测性能会因感应的机械应力和变形而发生变化和下降。在此，报告了一种具有弯曲不灵敏性的高性能，透明的纳米力触摸传感器。这是通过开发薄的，柔性的和透明的分层纳米复合薄膜来实现的，该薄膜由纳米结构的塑料基底，共面电极，以及具有银纳米颗粒的介电聚合物层。制造过程很简单，可以在大面积（8英寸）规模上实现高制造重复性，均匀性和可靠性。制成的设备的压力灵敏度为0.036 kPa^-1在高达3 kPa的压力范围内具有高透明度（83％）。尤其是，其薄的厚度（45 µm）和共面电极能够实现出色的对弯曲的不敏感性，其曲率半径为4 mm超过10000倍。
