摘要： A bio-inspired device is provided, designed to scale smooth vertical surfaces using anisotropic frictional materials. The device draws its inspiration from geckos and other climbing lizards and employs similar compliance and force control strategies to climb (or hang onto) smooth vertical surfaces including glass, tile and plastic panels. Foremost among the design features embodied in the device are multiple levels of compliance, at length scales ranging from centimeters to micrometers, to allow the device to conform to surfaces and maintain large real areas of contact so that adhesive forces can support it. Structures within the feet ensure even stress distributions over each toe and facilitate engagement and disengagement of the adhesive materials. A force control strategy works in conjunction with the anisotropic adhesive materials to obtain sufficient levels of friction and adhesion for climbing with low attachment and detachment forces.

摘要： Aspects of various embodiments are directed to sensor apparatuses and methods thereof. An example sensor apparatus includes a capacitor and sensor circuitry. The capacitor includes a first substrate having a first electrode, a second substrate having a second electrode, and a dielectric layer. The dielectric layer has a plurality of apertures arranged in a pattern, the first and second electrode being separated by the dielectric layer and arranged with an overlapping area with respect to one another. The sensor circuitry is coupled to the capacitor and configured and arranged to detect normal and shear forces applied to the sensor apparatus based on changes in capacitance derived from changes in at least one of a distance between the first and second electrodes and the overlapping area of the first and second electrodes.

摘要翻译：提供了一种生物启发装置，旨在使用各向异性摩擦材料缩放平滑的垂直表面。该设备从壁虎和其他爬山蜥蜴的灵感中吸取灵感，并采用类似的顺应性和力控制策略来攀爬（或悬挂）平滑的垂直表面，包括玻璃，瓷砖和塑料面板。器件中体现的设计特征中最重要的是多个级别的顺应性，长度范围从厘米到微米，以允许设备符合表面并保持大的实际接触区域，使得粘合力可以支撑它。脚内的结构确保每个脚趾上均匀的应力分布，并有助于粘合剂材料的接合和分离。力控制策略与各向异性粘合剂材料结合使用，以获得足够的摩擦力和粘合力，以较低的附着力和分离力进行攀爬。
