Abstract

Abstract: Flexible and wearable electronics has presented an opportunity to evolve our society into an intelligent world. Especially for biomechanical sensing and gesture recognition, wearable devices are quite indispensable. Here, we present a nestable arched triboelectric nanogenerator (NA-TENG), which can be wore on fingers, acting as a large deflection biomechanical sensor and energy harvester. With arched structure, the sensor can detect large bending angle of fingers with good stability. Meanwhile, the NA-TENG devices can be assembled like matryoshka, which greatly increases the extensibility for optimizing output performance of the NA-TENG, and provides a convenient method to regulate characteristics of TENG devices in wearable applications. Graphical abstract: The Nestable Arched Triboelectric Nanogenerator (NA-TENG) is demonstrated to be a large angle deflection biomechanical sensor and it can be assembled like matryoshka which greatly increases the extensibility for optimizing output performance. The nestable TENG can be applied in the future wearable electronics and robots, where various ingenious gesture sensors can be fabricated to be wore on hands and be integrated in robotic arms more conveniently. Image 1 Highlights: The nestable arched triboelectric nanogenerator can act as a large deflection biomechanical sensor and energy harvester. The NA-TENG can detect large bending angle of joint activity, including finger, wrist elbow and so on. The devices can be assembled like matryoshka to optimize output performance of the NA-TENG. It can regulate characteristics of TENG type of devices in wearable applications in a convenient way.
