Abstract
A novel single-layer structured triboelectric generator (TEG) is proposed with a hybrid mix of carbon nanotube (CNT) and silk. Here, the mixing of two materials in liquid phase for proven effective power generation is shown. In this research, CNT provides the function of conductivity, whereas silk fibroin forms the main triboelectric generation material that is uniformly mixed with CNT, to achieve a conductive film with superior electric power generation capability. The newly proposed TEG shows very good electrical performance and great potential in simplifying TEG’s structure and manufacturing process, enhancing their feasibility in future wearable applications.

carbon nanotube (CNT) provides the function of conductivity, whereas silk fibroin forms the main triboelectric generation material that is uniformly mixed with CNT, to achieve a conductive film with superior electric power generation capability
Wearable Electronics have promising applications in various fields ranging from self-powered sensors [1], wellness monitors [2] to shape adaptive electronics [3] as Internet of Things becoming developed
Experimental results To verify the effectiveness of the mixing-layered system as well as to allow it to provide enough power for wearables, a series of optimal parameters were verified through several sets of experiments
Summary
Wearable Electronics have promising applications in various fields ranging from self-powered sensors [1], wellness monitors [2] to shape adaptive electronics [3] as Internet of Things becoming developed. Owing to the conventional batteries lacking of the required properties such as flexibility, light weight, convenience and uniform specification, TEG as a self-sufficient power supplying source has become a most ideal and promising solution. There have been studies that have achieved some results for wearable TEGs [7,8,9], it is still difficult to balance softness, safety, cost, and application requirements. The complicated fabrication process to turn the uncomforting friction materials and metal into wearable will increase the cost and hinder TEG’s development in vast application as well. By the method of simple coating-peeling, a light-weight and soft mixed layer could be obtained for wearing and generating electricity power along with random human motions.
