3D-Printed Superhydrophobic and Magnetic Device That Can Self-Powered Sense A Tiny Droplet Impact Article

Xuan Zhang, Qi Wang, Ruiping Zou, Bo Song, Chunze Yan, Yusheng Shi, Bin Su

Engineering 2022, Volume 15, Issue 8,   Pages 197-206 doi: 10.1016/j.eng.2022.04.009

Abstract:

Three-dimensional (3D)-printed magnetic soft architectures have attracted extensive attention and research from the engineering and material fields. The force-driven shape deformation of such architectures causes a change in the magnetic field distribution, indicating the capability to convert mechanical energy to electricity. Herein, we fabricate a flexible superhydrophobic and magnetic device by integrating two kinds of 3D printing approaches. The 3D-printed magnetic device (3DMD) exhibits a long-term stable mechanoelectrical conversion capacity under consecutive water droplet dripping. The output current of the 3DMD is higher than that of records in the existing literature. Combined with Maxwell numerical simulation, the mechanoelectrical conversion mechanism of the 3DMD is investigated, further guiding regulation of the diverse parameters. Moreover, three 3DMDs are integrated to light up a commercial light-emitting diode (LED) by a stream of collected rainwater. Such a combined design incorporating energy conversion is believed to promisingly motive advances in the 3D printing field.

Triboelectric nanogenerators: the beginning of blue dream

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 6,   Pages 635-678 doi: 10.1007/s11705-022-2271-y

Abstract: Wave energy is inexhaustible renewable energy. Making full use of the huge ocean wave energy resources is the dream of mankind for hundreds of years. Nowadays, the utilization of water wave energy is mainly absorbed and transformed by electromagnetic generators (EMGs) in the form of mechanical energy. However, waves usually have low frequency and uncertainty, which means low power generation efficiency for EMGs. Fortunately, in this slow current and random direction wave case, the triboelectric nanogenerator (TENG) has a relatively stable output power, which is suitable for collecting blue energy. This article summarizes the main research results of TENG in harvesting blue energy. Firstly, based on Maxwell’s displacement current, the basic principle of the nanogenerator is expounded. Then, four working modes and three applications of TENG are introduced, especially the application of TENG in blue energy. TENG currently used in blue energy harvesting is divided into four categories and discussed in detail. After TENG harvests water wave energy, it is meaningless if it cannot be used. Therefore, the modular storage of TENG energy is discussed. The output power of a single TENG unit is relatively low, which cannot meet the demand for high power. Thus, the networking strategy of large-scale TENG is further introduced. TENG’s energy comes from water waves, and each TENG’s output has great randomness, which is very unfavorable for the energy storage after large-scale TENG integration. On this basis, this paper discusses the power management methods of TENG. In addition, in order to further prove its economic and environmental advantages, the economic benefits of TENG are also evaluated. Finally, the development potential of TENG in the field of blue energy and some problems that need to be solved urgently are briefly summarized.

Wearable thermal energy harvester powered by human foot

Frontiers in Energy 2013, Volume 7, Issue 1,   Pages 26-38 doi: 10.1007/s11708-012-0215-9

Abstract: With explosive applications of many advanced mobile electronic devices, a pervasive energy system with long term sustainability becomes increasingly important. Among the many efforts ever tried, human power is rather unique due to its independence of weather or geographical conditions and is therefore becoming a research focus. This paper is dedicated to demonstrate the possibility and feasibility of harvesting thermal energy from human body by sandwiching a thermoelectric generator (TEG) between human shoe bottom and ground, aiming to power a portable electronic device. Through the conceptual experiments conducted on adults, a maximum 3.99 mW steady state power output at a ground temperature with 273 K is obtained, which is sufficient enough to drive a lot of micro-electronic devices. Also, parametric simulations are performed to systematically clarify the factors influencing the TEG working performance. To further reveal the mechanism of this power generation modality, analytical solutions to the coupled temperature distributions for human foot and TEG module are obtained and the correlation between TEG characteristics and the output power are studied. It was demonstrated that, the TEG working as a wearable power resource by utilizing thermal energy of human foot shows enormous potential and practical values either under normal or extreme conditions.
