The paper-based flexible touch sensor comprises a first assembly, a second assembly and a third assembly, wherein the first assembly is composed of a paper-based insulating layer and a first metal conducting layer deposited on the surface of the paper-based insulating layer, the second assembly is composed of a paper-based insulating layer and a second metal conducting layer deposited on the surface of the paper-based insulating layer and an electret material layer coating the surface of the paper-based insulating layer together, and the third assembly is connected between the first assembly and the second assembly and is embodied in the form of an isolation layer with multiple holes. The invention further discloses a corresponding manufacturing method. By means of the paper-based flexible touch sensor and the manufacturing method, high power and high flexibility can be obtained with the obtained touch sensor serving as an active sensor, the whole touch sensor is easy to fold and bend and can be integrated with other flexible electronic devices, and therefore the touch sensor can be integrated with other flexible electronic devices and suitable for daily life application.

Description

technical field [0001] The invention belongs to the technical field of touch sensor devices, and more specifically relates to a paper-based flexible touch sensor and a manufacturing method thereof. Background technique [0002] Touch sensors, as a data input device, are currently widely used in electronic devices such as smartphones, tablets, laptops, and Ipads. Existing touch sensors can be mainly classified into capacitive touch sensors, resistive touch sensors, surface wave touch sensors and infrared touch sensors according to their working principles. With the performance requirements for lighter, thinner, and faster electronic products, rigid touch sensors are increasingly being replaced by flexible touch sensors to meet more attractive touch designs. [0003] However, the substrates of existing flexible touch sensors are mainly based on flexible materials of polymers, and are prepared according to capacitive sensing, piezoresistive or piezoelectric effects, and the li...
