摩擦纳米发电机(TENG)技术与传统纺织品的融合,为智能纺织品带来了新的活力和更多的应用方向。然而基于纺织品的TENG输出仍处于较低的水平,织物结构上的导电层影响电荷传输可能是原因之一。本文从织物基摩擦纳米发电机的导电层和特殊间隔织物结构研究出发,综述了摩擦纳米发电机的织物电极的制备方法,以及其在间隔织物TENG的应用现状。在此基础上,讨论了织物电极阻碍其输出的潜在困难和严峻挑战。希望不仅能在一定程度上加深智能纺织品与TENG之间的联系,也能为未来可穿戴TENG的相关研究和应用提供一些参考。 相似文献

Polymeric optical fibres (POFs) can be integrated into a textile structure for illuminative fashion and interior fabric applications. In this study, the development of a touch-sensitive POF fabric system through the integration of conductive yarns and an electronic controlling system was explored. Distinct from conventional sensor applications, the capacitive sensor used in this study was embedded into the textile structure using conductive yarns via experimentations with different weave structures. With the embedded controlling system and RGB light-emitting diodes, the POF fabrics were able to transfer sensory signals into illumination. This study combined novel weaving techniques, different materials and electronic system development to develop a multi-touch interface based on textile capacitive sensors that can sense both touch contact and non-contact/proximity. The final prototype can be washed up to 10 laundry cycles. The results demonstrated that multiple functionalities can be integrated into the structure to produce an interactive textile based product. 相似文献

In this paper, a stitched fabric for decoding the pressure distribution information by means of resistive sensing is introduced. The proposed fabric-structured sensor is constructed by a distributed resistive array of two orthogonally contacted electrical conductive yarns system, which needs not any external sensing elements to be attached on the fabric. The conductive yarns served as the sensing and wiring elements simultaneously, which in turn simplify the fabrication process and decrease the cost, make the production of large area flexible pressure sensor possible. The topology of the sensing elements distributed on the fabric can be set by stitching the conductive yarn on the substrate fabric by sewing or embroidery machine. The location and pressure applied on the fabric can be obtained by detecting the position where the change of the resistances occurs between two embroidered yarns system. Meanwhile, the magnitude of the pressure can be acquired by measuring the variations of the resistance under pressure. Coating is applied on the contact points of the two yarns system to increase the sensitivity and stability. It is found from the experimental results that the sensitivity and stability are improved dramatically after coating. The resistance vs. pressure exhibits a nonlinear “two stages” mode and the contacting resistance is unstable at small pressure region. The electronics system that picks up the signal of the resistance matrix is also introduced. Flexible, robust, light weight, and breathable provide the sensor advantages to be used as wearable sensors. Meanwhile, easy fabrication and low costs make large area sensing such as sensing carpet possible. 相似文献
