“…By integrating two kinds of mechanical energy harvesting units, a composite mechanical energy harvesting technology is widely used to improve the overall output power of energy devices. − The core idea is to acquire more electricity through mechanical movement. The TENG can collect mechanical energy through the contact–separation of two friction materials, and the EMG generates electrical energy through the relative movement between the magnet and the coil.…”

The hybrid of a triboelectric nanogenerator (TENG) and an electromagnetic generator (EMG) has been shown to be an effective approach toward harvesting vibration energy. Therefore, in this work, a triboelectric–electromagnetic hybrid energy harvester based on magnetic liquid is proposed. The magnetic liquid (prepared by Beijing Shenran Magnetic Fluid Co., Ltd) is made with water, an active agent, and ferromagnetic particles. Electrostatic induction between the polymer sidewall and the solvent water activates a triboelectric generator component, while electromagnetic induction between the suspended ferromagnetic particles and an outer coil activates the electromagnetic generator component. Initially, the harvester is deduced theoretically to show the feasibility of the design. Then, the output performance of the energy harvester is fully investigated under various dynamical experiments. Finally, experimental results show that the hybrid energy harvester has very low threshold amplitude and wide operating frequency range, both of which can be particularly advantageous for harvesting subtle and irregular vibrations.

Vibration is one of the widespread phenomena in our surroundings, and a lot of research has been conducted to harvest it; however, due to its low frequency and random directions, there are few solutions to achieve omnidirectional energy harvesting. Based on a tower spring, this paper proposes an omnidirectional hybrid triboelectric–electromagnetic nanogenerator (OD-HNG) to harvest the omnidirectional vibration energy. The triboelectric nanogenerators (TENGs) are designed into a multilayered structure to enhance space utilization, and the electromagnetic generator (EMG) unit is hybridized to increase the output of OD-HNGs further. Benefiting from the design of the tower spring, the OD-HNG can respond to the external excitation in both vertical and horizontal directions, and its operational bandwidth is extended, allowing it to perform omnidirectional and broadband vibration energy harvesting very effectively. When OD-HNG is installed on a bicycle at a regular riding speed, a 1000 μF capacitor can be charged to 1.75 V in 20 s and has been successfully used as the power supply of portable electronic devices, ambient temperature monitors, and self-powered systems. More significantly, by harvesting the vibration energy from the vehicle-mounted environment, the OD-HNG can power portable electronic devices and environmental sensors continuously. These characteristics show that the tower spring-based OD-HNG is capable of very effective omnidirectional and broadband vibration energy harvesting and provides a good candidate for harvesting low-frequency vibration energy on a large scale.

Triboelectric nanogenerators (TENGs) to harvest ocean wave blue energy is flourishing, yet the research horizon has been limited to centimeter‐level TENG. Here, for the first time, a TENG shell is advanced for ocean energy harvesting to 0.5 m and an excellent frictional areal density of 1.03 cm−1 and economies of scale are obtained. The unique structure of the multi‐arch shape is adopted to untie the difficulty of fully getting the extensive friction layer contact. An inside steel plate is vertically placed in the center of every TENG block, which can activate the TENG to achieve complete contact even at a tilt angle of 7 degrees. The proposed half‐meter TENG (HM‐TENG) has a broad response band from 0.1 to 2 Hz, a total transferred charge quantity up to 67.2 µC, and one single TENG can deliver an open‐circuit voltage of 368 V. Coupled with the self‐stabilizing and susceptible features the ellipsoid shell brings, the HM‐TENG can readily accommodate itself to the all‐weather, all‐sea wave energy harvesting. Muchmore, the HM‐TENG is also applied to RF signal transmitters. This work takes the first step toward near‐meter‐scale enclosures and provides a new direction for large‐scale wave energy harvesting.
