A soft touch Measuring the force it takes for a hand to grasp an object requires sensors to be placed on the fingertips, but these sensors will interfere with or affect how much force ends up being applied. Lee et al. developed a nanomesh sensor built from a series of electrospun materials (see the Perspective by Liu). Using a robotic tester, they show that this device can repeatably detect the pressure involved in gripping an object. They also show that the sensors can be attached to human fingers and that this does not affect the force used to grasp an object. Science, this issue p. 966; see also p. 910 Human skin can be electrically functionalized with sensors, without affecting human sensation. Monitoring of finger manipulation without disturbing the inherent functionalities is critical to understand the sense of natural touch. However, worn or attached sensors affect the natural feeling of the skin. We developed nanomesh pressure sensors that can monitor finger pressure without detectable effects on human sensation. The effect of the sensor on human sensation was quantitatively investigated, and the sensor-applied finger exhibits comparable grip forces with those of the bare finger, even though the attachment of a 2-micrometer-thick polymeric film results in a 14% increase in the grip force after adjusting for friction. Simultaneously, the sensor exhibits an extreme mechanical durability against cyclic shearing and friction greater than hundreds of kilopascals.

Nanomesh 压力传感器，用于在没有感官干扰的情况下监测手指操作

轻触 测量手抓住物体所需的力需要在指尖上放置传感器，但这些传感器会干扰或影响最终施加的力的大小。李等人。开发了一种由一系列电纺材料制成的纳米网传感器（参见 Liu 的观点）。他们使用机器人测试仪表明，该设备可以重复检测抓握物体所涉及的压力。他们还表明，传感器可以连接到人的手指上，并且这不会影响用于抓握物体的力。科学，这个问题 p。966; 另见第 910 人体皮肤可以通过传感器进行电功能化，而不会影响人体感觉。在不干扰固有功能的情况下监控手指操作对于理解自然触感至关重要。然而，磨损或连接的传感器会影响皮肤的自然感觉。我们开发了纳米网压力传感器，可以监测手指压力，而不会对人体感觉产生可检测的影响。传感器对人类感觉的影响进行了定量研究，应用传感器的手指表现出与裸手指相当的握力，即使 2 微米厚的聚合物薄膜的附着导致 14% 的增加调整摩擦后的握力。同时，该传感器对超过数百千帕的循环剪切和摩擦表现出极高的机械耐用性。传感器对人类感觉的影响进行了定量研究，应用传感器的手指表现出与裸手指相当的握力，即使 2 微米厚的聚合物薄膜的附着导致 14% 的增加调整摩擦后的握力。同时，该传感器对超过数百千帕的循环剪切和摩擦表现出极高的机械耐用性。传感器对人类感觉的影响进行了定量研究，应用传感器的手指表现出与裸手指相当的握力，即使 2 微米厚的聚合物薄膜的附着导致 14% 的增加调整摩擦后的握力。同时，该传感器对超过数百千帕的循环剪切和摩擦表现出极高的机械耐用性。
