Coil design is important for maximizing power density in inductive energy harvesting as well as in inductive power transfer. In this work, we present a study of coil performance, based on simulated flux distributions corresponding to a real aircraft application case. The use of funnel-shaped soft magnetic cores boosts magnetic flux density by flux concentration and allows the use of a smaller diameter coil. This reduces the transducer mass as well as the coil resistance $(R_{COIL})$, thereby increasing the power density. Analysis and simulation shows a fifty-fold power density increase from moderate funneling and another two-fold increase by coil size optimization. Results are compared with experimental measurements presented in [1] which demonstrate a $mu mathrm{W} / mathrm{g}left(106 mu mathrm{W} / mathrm{cm}^{3}right)$ power density from alternating environmental magnetic fields in the $10 mu mathrm{T} /300$ Hz range.
线圈设计对于在感应能量收集和感应功率传输中最大化功率密度非常重要。在这项工作中，我们提出了一个研究线圈的性能，基于模拟磁通分布对应于一个真实的飞机应用情况。漏斗形软磁芯的使用通过磁通浓度提高了磁通密度，并允许使用较小直径的线圈。这减少了换能器质量以及线圈电阻$(R_{COIL})$，从而增加了功率密度。分析和仿真表明，适当的漏斗可使功率密度提高50倍，优化线圈尺寸可使功率密度提高2倍。结果与[1]中提出的实验测量结果进行了比较，该测量结果显示了$10 mu mathrm{T} /300$ Hz范围内交变环境磁场的$mu mathrm{W} / mathrm{g}left(106 mu mathrm{W} / mathrm{cm}^{3}right)$功率密度。

This paper focuses on the design parameters of the thermal connection for a thermoelectric energy harvesting system mounted onto endothermic animals. To the best of our knowledge, this is the first time that the thermal conductivity through a mammal’s fur is analyzed with a specially designed heatsink. An analytical model is built to predict the resulting thermal resistances and is validated with experimental results for two different fur lengths. We show that an optimized design of the thermal interface reduces its thermal resistance up to 38% compared to a trivial design while lowering its weight for about 23%. It is found that the most important design parameter of such a thermal connector is the ability to slide into the fur.

Radioisotope generators can provide power for several decades without the need of any further energy input, such as solar or chemical energy. A portable radioisotope generator can foresee many applications in future military and civilian uses that require minimum access and maintenance, such as to power sensors in a polar region, on a floating buoy, or undersea. In this work, we report the design, simulation, and measurement results of the thermal insulation of a miniaturized radioisotope system. We tested a prototype powered by an electrical heater with the same size as a plutonium fuel pellet. We tested the material compatibilities and showed the designs suitable for generators using thermoelectric and thermophotovoltaic converters respectively. In addition, we proposed a new insulation that uses a layered dielectric’s omni-directional reflectivity as a futuristic insulation mechanism to shield radiation heat for micro to meso-scale thermal systems.

There is a vital need to develop technologies to dynamically harvest energy from surroundings to power IoT applications [1]. Thermoelectrics is promising, since it enables utilization of ubiquitous thermal energy like body heat [2]. In regards to viable thermoelectric applications, the performance (high Figure of merit ZT) of the materials is important, but likewise critical is the appropriate processing and fabrication methods of effective modules. The cheapness of materials can usually not justify poor thermoelectric performance since the cost of viable materials is typical not the major cost in the module production. Considering applicative issues, we have been developing two strategies, developing inorganic thermoelectric thin films, and developing hybrid or “sticky” inorganic-organic composite materials [3]. The former using sputtering can be compatible to industrial processes and the thin film modules can be readily integrated into IoT devices. The latter can potentially enable roll to roll production of inexpensive large area sheets. I will present our work on these two strategies.

Recently, we developed self-assembled electret (SAE)-based vibrational energy generator (VEG) which can generate electrical power from ambient vibrations. An advantage of the device is that any charging process is not required for making electret, that is, surface potential (Vsp) of SAE naturally appears only by vacuum deposition. This is because the Vsp originates from spontaneous orientation of polar molecules such as Alq3 and TPBi. Thus, to increase output power of SAE-VEG, enhancement of order parameter of the molecule, $langle cos theta rangle$, is required. In this study, we prepared TPBi-based SAE films with various deposition rate (rdep). We found that the Vsp becomes 1.8 times larger in the case of high rdep of 4.0 Å/s, suggesting that molecular orientation can be controlled by rdep. This result indicates that further enhancement of output power in SAE-VEG can be realized through optimization of fabrication process of SAE.
最近，我们开发了基于自组装驻极体(SAE)的振动能量发生器(VEG)，它可以从环境振动中产生电能。该装置的优点是制备驻极体不需要任何充电过程，即SAE的表面电位(Vsp)仅通过真空沉积自然产生。这是因为Vsp来源于极性分子如Alq3和TPBi的自发取向。因此，为了提高SAE-VEG的输出功率，需要提高分子的序参量$langle cos theta rangle$。在本研究中，我们制备了不同沉积速率(rdeep)的tbi基SAE薄膜。我们发现，在4.0 Å/s的高rdep下，Vsp增大了1.8倍，这表明分子取向可以由rdep控制。结果表明，通过优化SAE的制造工艺，可以进一步提高SAE- veg的输出功率。

Photoelectrochemical cells, PEC represent an important class of devices generating solar-hydrogen and create an attractive alternative to the traditional power sources. Practical application of PEC is hindered by numerous drawbacks of semiconducting light absorbers, the most important being: a mismatch between the spectrum of Sun and the fundamental absorption of the semiconducting photoanode. This review is devoted to new solutions related to the light harvesting and charge transport issues in TiO2-based PEC. Light management based on fitting the sunlight spectrum to the sensitivity of the device via a wavelength-shift operation, such as up-conversion, is proposed. Charge transport schemes required to reduce electron-hole pairs’ recombination depend on the form of the photoanode material with 1D nanorods and nanotubes being considered the best suited for this purpose.

We show that conducting polymer Poly (3,4-ethylene dioxythiophene)/poly (styrene sulfonate) film could be an ideal electrode in thermo-electrochemical cells, which shows a low charge transfer resistance. Using ferricyanide/ferrocyanide as an electrolyte, the Poly (3,4-ethylene dioxythiophene)/poly (styrene sulfonate) based thermo-electrochemical cell could be used to drive light-emitting diodes array. The conducting polymers also show the advantage of hybrid insoluble redox couples such as Prussian blue analog materials, making it easy to measure the temperature-dependent redox potential. By a combination of proper redox couples, the thermally regenerative electrochemical cells could realize. The power could generate during the environmental temperature change.

In this study, we developed a triboelectric nanogenerator (TENG) for intelligent tires. This TENG was adhered on the inner surface of a racing cart tire. The charged voltage and output voltage of the TENG were evaluated on the moving belt. The output voltage signals were observed at the contact patch position. The charged voltage to the 10 µF capacitor of was found to be approximately 14 V at the speed of 16 km/h after the tire rolled for 15 min. These results suggest that TENG can work as an energy harvester for temperature and pressure sensors built into intelligent tires as well as for wireless transmission.

In this work, a facile and universal strategy to enhance the triboelectric output is proposed by the integration of a narrow-gap TENG textile (T-TENG) with a high-voltage diode and a textile-based switch. The closed-loop current of the diode-enhanced textile-based TENG (D-TENG) can be increased by 25 times, and the speed of the charging capacitor is 4 times larger than the conventional strategy. The soft, flexible, and thin characteristics of the D-TENG enable a moderate output under various operations even as it is randomly scrunched. Besides, the enhanced current can directly stimulate rat muscle and nerve. In addition, we demonstrate the capability of the D-TENG as a practical power source for wearable sensors by powering Bluetooth sensors for humidity and temperature sensing.

We proposed a thermoelectric generator (TEG) with origami-like folded structure called “origami-fin” in order to achieve both high heat radiation performance and high stretchability. Our origami-fin produces the stretchability of the TEG by local bending of non-stretchable material and works as a heat radiator because of its large surface area compared with a not folded flat structure. We evaluated a heat radiation performance of the origami-fin, and stability of the performance by stretching deformation. The results show that the origami-fin works as a heat radiator to enhance the output of the TEG, and has high stretchability with slight output reduction.
