“…Such potential problem could be resolved by additionally introducing the elastic layer below the contact layer, which enables the MS‐TENG to effectively endure such unexpected vibration with large amplitude. According to the literature, it is possible to develop another TENG unit, which has a structural elasticity due to its unique structure, called a double‐helix structure 49,50 . The addition of such TENGs to our original MS‐TENG allows us to additionally generate the electricity from the large and strong vibrations and this effective reduction of energy losses with advanced durability under strong vibration enhances the output performance as well as the structural durability as shown in Figures S4 and S5.…”

Vibration energy, which is ubiquitous but usually abandoned energy, has been considered as a promising source of energy to be harvested for future power supply to electronics. In this study, we demonstrate the triboelectric nanogenerator (TENG) with a rationally designed bi-axial vibration responsive magnetic configuration (BVMC). Oblique placement of two magnets enables the system to be bi-axially sensitive and the superior response of such BVMC to vibrations is explored for further utilized to harvest multidirectional vibration energy in a single device. Energy harvesting performance of the multidirectional vibration stimuli-responsive TENG, called MS-TENG, under various vibration conditions is investigated. In addition, the further development of the MS-TENG with an additional magnet exhibits the full (threedimensional) vibration energy harvesting ability. The MS-TENG is applied under-the-hood of an automobile where typically abandoned vibrations occur frequently. Turning on the engine on the ignition enables the arrayed MS-TENG to generate a stable output just by engine trembling. Furthermore, the normal human motion-driven vibration is used to charge the commercial capacitor to wirelessly transmit the signal including information of ambient temperature and humidity from the Bluetooth thermo-hygrometer sensor. Consequently, the present TENG with simple but bi-axially sensitive magnetic configuration has a great potential to effectively harvest the multidirectional and low-frequency vibrations around us for future feasible applications.

The increasing amount of Internet of Things (IoT) devices and wearables require a reliable energy source. Energy harvesting can power these devices without changing batteries. Three-dimensional printing allows us to manufacture tailored harvesting devices in an easy and fast way. This paper presents the development of hybrid and non-hybrid 3D printed electromagnetic vibration energy harvesters. Various harvesting approaches, their utilised geometry, functional principle, power output and the applied printing processes are shown. The gathered harvesters are analysed, challenges examined and research gaps in the field identified. The advantages and challenges of 3D printing harvesters are discussed. Reported applications and strategies to improve the performance of printed harvesting devices are presented.

“…If this energy is converted into electricity, it can meet the power consumption for part of wearable electronics [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. As an emerging energy conversion technology, triboelectric nanogenerators (TENG) have been widely used in the field of self-powered wearable electronics because of their low cost, environmental friendliness, and flexibility [ 18 , 19 , 20 ]. A TENG can provide an effective approach to converting such biomechanical energy into electrical energy to provide power for part of wearable electronics, thus constructing a self-powered human motion signal monitoring and recognition system [ 21 , 22 , 23 ].…”

Energy-harvesting devices based on a single energy conversion mechanism generally have a low output and low conversion efficiency. To solve this problem, an energy harvester coupled with a triboelectric mechanism and electrostatic mechanism for biomechanical energy harvesting is presented. The output performances of the device coupled with a triboelectric mechanism and electrostatic mechanism were systematically studied through principle analysis, simulation, and experimental demonstration. Experiments showed that the output performance of the device was greatly improved by coupling the electrostatic induction mechanisms, and a sustainable and enhanced peak power of approximately 289 μW was produced when the external impedance was 100 MΩ, which gave over a 46-fold enhancement to the conventional single triboelectric conversion mechanism. Moreover, it showed higher resolution for motion states compared with the conventional triboelectric nanogenerator, and can precisely and constantly monitor and distinguish various motion states, including stepping, walking, running, and jumping. Furthermore, it can charge a capacitor of 10 μF to 3 V within 2 min and light up 16 LEDs. On this basis, a self-powered access control system, based on gait recognition, was successfully demonstrated. This work proposes a novel and cost-effective method for biomechanical energy harvesting, which provides a more convenient choice for human motion status monitoring and can be widely used in personnel identification systems.
