The concept of the electromagnetic energy harvesting by thermoelectric system based on a broadband metal-insulator-metal-based metamaterial combined with a magnetic tunnel heterostructure, exhibiting the tunnel magneto-Seebeck effect, is presented. Based on finite-element calculations, the optimal design of such a broadband metamaterial with conductive TiN layer was selected to ensure maximum adsorption of radiation in a given wavelength range (solar spectrum/microwave region). The microwave heating of the magnetic tunnel heterostructure after passing the electromagnetic wave through the metamaterial and corresponding thermo-voltage response were also evaluated, indicating the possibility of using such system for an effective energy supply of low-power electronic devices.

The concept of Internet of Things (IoT), sets a list of challenges we have to face for its fully functioning. One of them is power supply. In off-grid systems, the demand on the autonomous power generators is really high. In this paper we present for the first time inkjet 3D printed vibration power microgenerator. The principle of electricity generation in presented energy harvester relies on the electromagnetic induction of electricity in coil by vibrating magnet. Magnet is suspended on 3D printed microsprings. The device exhibits the highest generated voltage value in microspring resonant frequency (~250 Hz) and is equal to 0,5 V with output counted in mW. Microspring resonant frequency can be easily adjustable by changing their dimensions during designing step and 3D printing.

A supercapacitor (SC) stores the energy basing on physical phenomena resulting in the formation of an angstrom-thick electrical double layer between the electrode surface and liquid electrolyte. Thanks to this, the SCs offer a long lifetime (up to about 104 hours)and - regarding such parameters as energy and power densities - they are located between fast electrolytic capacitors and slow batteries [1, 2]. Therefore, the SCs are considered as a power supply for many tiny devices [3]. However, the issue is how to preserve their impressive performance as they are encapsulated. One of the potential solutions is to encapsulate the SC components in silicon-based polymer, polydimethylsiloxane (PDMS), which constitutes the substitute for glass with additional properties – flexibility and easily shaping by so-called mold technique [4–6]. So far in most of the present works gel- or solid-type electrolyte has been used. Because of their higher viscosity - compared to the liquid electrolyte – there is a facile control over an encapsulation process. On the other hand, it can not guarantee the as fast flow of ions between the electrodes as a liquid electrolyte. In a consequence, the high-rate charging of the SC is diminished.

This paper investigates the main design constraints for the optimisation of an inductive power transfer (IPT) link for recharging implantable medical devices [1], and presents the potential advantages of operating in the multi-MHz range for such applications. The design proposed in this paper offers a fast charging solution, allowing patients to recharge their active medical implants every 4-5 years for 40% of its battery capability. The main challenge consists of obtaining good coupling and effective Q factor of the receiver coil, while minimizing the overall increase in size of the medical implant. Analysis obtained through electromagnetic simulations with CST Studio Suite for a 13.56 MHz, 1 W system suggests that it is possible to achieve a relatively high theoretical link efficiency of 66%, while keeping surface temperature increases and specific absorption rate (SAR) within the limits established in EN 45502 [2] and ICNIRP 1998 [3]. The experimental results show two feasible systems with different separation distances between the device’s metallic case and the receiver coil, achieving transfer efficiencies [11] of 41% and 53% for separations of 1 mm and 7 mm, respectively.
本文研究了用于为植入式医疗设备充电的感应功率传输(IPT)链路优化的主要设计约束[1]，并提出了在此类应用中在多mhz范围内工作的潜在优势。本文提出的设计提供了一种快速充电解决方案，允许患者每4-5年为其活性医疗植入物充电40%的电池容量。主要的挑战包括获得良好的耦合和接收线圈的有效Q因子，同时最小化医疗植入物的整体尺寸增加。通过CST Studio Suite对13.56 MHz, 1 W系统进行电磁模拟分析表明，可以实现66%的相对较高的理论链路效率，同时保持表面温度升高和比吸收率(SAR)在EN 45502[2]和ICNIRP 1998[3]中规定的范围内。实验结果表明，两种可行的系统在器件的金属外壳和接收线圈之间具有不同的分离距离，在1 mm和7 mm的分离距离下，传输效率[11]分别为41%和53%。

This paper reports the experimental bandwidth enhancement of a PMN-PT-based strongly-coupled piezoelectric generator exhibiting softening nonlinearities associated to a tunable electrical load. The frequency bandwidth of the harvester associated to a R-tuning technique increases from 3.5% to 12.3% as the acceleration level increases, while it increases from 10.1% to 12.3% with a RC-tuning technique. Then, we show that the exploitation of nonlinearities highly increases the harvesting bandwidth with R-tuning techniques, competing with RC-tuning ones at high-acceleration levels.

A broadband vibration energy harvester tailored for self-powered condition monitoring of underground trains is proposed and developed using mechanical non-linearity and integrated multi-mode vibration. A data-driven approach is adopted for harvester design using operational vibration data on a train bogie. The harvester is designed to be unobtrusive while exhibiting good performance in harvesting energy over a wide bandwidth. In this work, the on-site vibration data are first analysed with the design goals identified. Then, a broadband harvester is proposed, implemented and evaluated. The harvester consists of a pre-stretched hosting beam and a group of micro-beams with repulsive magnetic forces on their free ends. A multiple vibration-mode harvester with non-linear dynamics is obtained in such a design. This harvester exhibits good performance over a broad bandwidth in frequency sweep and pseudo-random tests, illustrating its capability in self-powered condition monitoring applications.

This paper presents an electret-based energy harvester for leadless pacemakers by harvesting energy from the ventricular blood pressure using a PDMS/parylene electret on the surface of the cylindrical device. The proposed device has the advantage that the space within the inner cylindrical electrode can be used to accommodate the pacer electronics so that the harvester and the pacemaker can be integrated into a single device. The device design, fabrication and charging techniques of the tubular PDMS/parylene electret are presented. Preliminary tests of a prototype harvester showed 0.25 $mu$W output to a matched 80 G$Omega$ load for ± 63 mmHg pressure variation at 1 Hz.

Thermionic energy conversion represents a simple and elegant approach for harvesting heat to generate electricity. This conversion mechanism has been known for over a century and has experienced several waves of interest in research and development. However, significant challenges related to materials properties and fabrication technologies have prevented the creation of efficient and practical devices, hindering broad adoption of this concept.In this presentation, the fundamentals of thermionic energy conversion will be reviewed and the parameters affecting converter performance discussed. Some of the past device examples will be briefly looked at and their challenges highlighted. Over the last two decades, interest in thermionic energy conversion has gradually resurfaced due to the advances in materials and fabrication processes, which have provided opportunities for addressing the long -standing challenges in this field. Several of the key recent developments will be described and the current status and future outlook discussed. It will be seen that new effects and nanomaterials sometimes necessitate a more sophisticated experimental approach to the study of their fundamental properties for thermionic emission and conversion than commonly used in the past.

In this paper, we report a 3D printed hybridized nanogenerator which can convert the in-plane arbitrary motions and vibrations into useful electrical energy. Also, it can detect in-plane arbitrary motions and vibrations effectively. The proposed device consists of a central magnet based hybridized electromagnetic (EMG) and triboelectric nanogenerator (TENG) and the repulsive force from central magnet drives the four side magnets for self-powered motion sensors (MS1, MS2, MS3 and MS4). The EMG and TENG generates the peak power of 18 mW at 193 $Omega$ and 3.25 $mu$ W at 10.5 M$Omega$ load resistance, respectively. The proposed motion sensor is capable of sensing arbitrary motion in 3-axis directions. With the integration of motion sensing capability as well as energy harvesting on the same device, a complete self-powered sensor system has been successfully demonstrated.

We report novel, low-cost, high-temperature compatible, high-pressure compatible, and chemically resistant 3D printed microfluidics suitable for microreactors, heat exchangers, and other PowerMEMS applications. The devices are manufactured via silver clay extrusion; optimization of the printing method results in linearity between printed and computer-aided design (CAD) features, with $sim 11$% (printed positive features, i.e. solid) and $sim 12$% (printed negative features, i.e. voids) shrinking from CAD values after firing. Printed gaps as narrow as $200 mu mathrm{m}$ were demonstrated, which are adequate to implement closed-channel microfluidics. A proof-of-concept microreactor that decomposes hydrogen peroxide was designed, fabricated, and characterized, demonstrating 86% efficiency with initial 30% hydrogen peroxide (w/w) in water concentration.

The devices are manufactured via silver clay extrusion; optimization of the printing method results in linearity between printed and computer-aided design (CAD) features, with $sim 11$% (printed positive features, i.e. solid) and $sim 12$% (printed negative features, i.e. voids) shrinking from CAD values after firing. Printed gaps as narrow as $200 mu mathrm{m}$ were demonstrated, which are adequate to implement closed-channel microfluidics.
