Abstract Full text Electronic supplementary material About this article

Triboelectric interfaces have already been extensively researched in the area of human–machine interaction owing to their self-sustainability, low cost, easy manufacturing, and diverse configurations. However, some limitations (e.g., a large number of electrodes, multiple lines, and chunks) observed in previous works hinder the further development of human–machine interaction applications. Herein, a triboelectric encoding interface is proposed by designing the reverse polarity of the tribo-layers to encode the triboelectric output signals. Owing to the inversion of the tribo-layers and the number of strip electrodes, this encoding method can realize multipurpose interactive commands by using fewer electrodes and a simple structure only in one macroscopic triboelectric device, which greatly reduces the size of the device as well as the influence of external factors on the coded signal output. As a demonstration, a ring with the patterned triboelectric interface (15 mm × 20 mm) achieves slide presentation and remote electric device control. In addition, the triboelectric sensor has good sensitivity (1.55 V/N) and durability (> 30,000 cycles). This new encoding mode shows the high applicability of the operation mode in diversified interactive applications, which provides more design strategies for intelligent control.

Abstract

Triboelectric interfaces have already been extensively researched in the area of human–machine interaction owing to their self-sustainability, low cost, easy manufacturing, and diverse configurations. However, some limitations (e.g., a large number of electrodes, multiple lines, and chunks) observed in previous works hinder the further development of human–machine interaction applications. Herein, a triboelectric encoding interface is proposed by designing the reverse polarity of the tribo-layers to encode the triboelectric output signals. Owing to the inversion of the tribo-layers and the number of strip electrodes, this encoding method can realize multipurpose interactive commands by using fewer electrodes and a simple structure only in one macroscopic triboelectric device, which greatly reduces the size of the device as well as the influence of external factors on the coded signal output. As a demonstration, a ring with the patterned triboelectric interface (15 mm × 20 mm) achieves slide presentation and remote electric device control. In addition, the triboelectric sensor has good sensitivity (1.55 V/N) and durability (> 30,000 cycles). This new encoding mode shows the high applicability of the operation mode in diversified interactive applications, which provides more design strategies for intelligent control.
