A highly sensitive and ultra-stretchable zwitterionic liquid hydrogel-based sensor as anti-freezing ionic skin

Soft conductors show great promise in multifunctional sensor applications. However, both electronically and ionically conductive materials are often vulnerable during large deformation or at low temperatures, leading to reduced sensitivity,...

MULTIFUNCTIONAL SENSOR BASED ON A PLANAR CAPACITOR FOR REMOTE SENSING

The article deals with the issues related to the technical implementation of environmental sensing using capacitive sensors. It proposes a design of a capacitive sensor of a planar type, and studies physical principles of its operation. The operation of the sensor in two main modes is analyzed: 1) determination of the distance to the object at known electrophysical characteristics of the object; 2) determination of the electrophysical characteristics of the object at a known distance to it. The article provides data of direct measurements of the sensor capacitance and its output signal level under various conditions.
