Abstract

Conductive Composite Elastomers

Conducting polymer composites can be fashioned into novel sensing applications such as robotic skins. However, such composites naturally form an insulating surface layer, and the fidelity of such sensors depends on having reliable ohmic contact through this insulating surface to the underlying touch-sensing layer. Explicit studies of this surface layer are therefore needed; in article number 2400848, Noa Lachman, Matthew A. Grayson, and co-workers not only demonstrate the characterization of this insulating surface layer and the challenges it poses to making good electrical contact, but also provide prescriptive tools for fabricating and testing such contacts for proper ohmic behavior.

深入传感器内部：导电复合弹性体电接触表征的重要性（Adv.）

导电复合弹性体导电聚合物复合材料可以制成新型传感应用，如机器人皮肤。然而，这种复合材料自然形成一个绝缘表面层，并且这种传感器的保真度依赖于通过该绝缘表面与底层触摸传感层具有可靠的欧姆接触。因此，需要对这一表层进行明确的研究；在2400848号文章中，Noa Lachman、Matthew A. Grayson及其同事不仅展示了这种绝缘表面层的特性，以及它对制造良好电接触所带来的挑战，而且还提供了制造和测试这种接触的规范工具，以获得适当的欧姆行为。机器人图像由西北大学手工工程研究中心实验室提供。
