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 ~11% (printed positive features, i.e. solid) and ~12% (printed negative features, i.e. voids) shrinking from CAD values after firing. Printed gaps as narrow as 200 μm 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.

We report the design, fabrication, and characterization of the first fully 3D-printed, multi-material, magnetically driven, valve-less miniature liquid pumps in the literature. Extending our work on 3D-printed liquid pumps [1] and magnetic actuators [2], the new devices are driven by a rotating magnet and employ valve-less diffusers [3]. Our leak-tight, miniature liquid pumps are microfabricated using 150 $mu$ m layers in pure Nylon 12 and NdFeB-embedded Nylon 12 via fused filament fabrication (FFF) [4] –an inexpensive additive manufacturing method for thermoplastics capable of monolithically creating multi-material objects. The fabrication of the pumps employs a novel multi-material printing process that monolithically creates all features with <13 $mu$ m in-plane misalignment. The new pumps occupy 4.3X less volume than our FFF printed embedded magnet pumps, while sustaining 20% larger flow rates and actuating 14X faster [1].

This paper proposes an interface circuit for a frequency up conversion piezoelectric energy harvester with OPAMP as core controller, which can increase output power by over 400% compared with full bridge circuit. Because of differential amplification characteristics of OPAMP, the failure of traditional logic gates zero-crossing detection circuit in low voltage is overcome. The advantage of frequency up conversion energy harvester is suitable for wide frequency bands, but output waveform is attenuating and oscillating, making circuit design difficult to detect zero-crossing point, causing low power efficiency. Innovations include: (1) Theoretical modeling method of frequency up conversion energy harvester (2) Power management circuit design method suitable for frequency up conversion energy harvester is proposed for the first time. Using OPAMP, control logic is effective in the case of harvester output attenuating and oscillating and current is low. (3) Method about how to choose device parameters.

In this paper, an efficient wind energy harvester (WEH) which simultaneously possesses both the advantages of simple structure and easy manufacture is designed. Proved by the simulation results, the WEH with air outlet at the top side not only effectively increases the rotational speed of the turbine but also obviously enhances the rotation stability of the blades, which eventually turn to improve the output performance of the device. According to experimental analysis, when the wind speed is 15 m/s, the proposed WEH can generate maximum output power of 40.7 mW, with corresponding power density of 0.3 mW/cm3. Last but not least, integrated with a switch-controlled circuit module and a low-powered angle sensor module, a self-powered wireless sensor node (WSN) is successfully established.

A triboelectric interacting patch with only four sensing electrodes is presented as flexible and multifunctional human-machine interface for the detection of various human-machine interactions. By leveraging the predefined operation areas, position detection under finger operations can be achieved through the output relationship of the four electrodes. The accurate sensing capability of the triboelectric patch is compatible with common finger motions such as finger tapping and sliding, opening up broad application in various interacting areas, e.g., writing interface, security code system, intuitive intelligent control, virtual/augmented reality, and robotics, etc.

This research presents a flexible, low cost ferroelectret integrated into a piece of ordinary textile. The textile ferroelectret is made of PDMS (polydimethylsiloxane)-ZnO (Zinc oxide) nanoparticle mixture that spin cast on both side of a textile. The PDMS-ZnO textile ferroelectret achieved 55% piezoelectric coefficient d33 remaining, compared with 35% of pure PDMS textile ferroelectret. The measured piezoelectric coefficient d33 of the PDMS-ZnO textile ferroelectret is maintained at 220 pC/N after two weeks.

Coupled wireless power transfer (WPT) has been widely used for near-field high-efficiency WPT applications. However, the efficiency of the WPT link is highly sensitive to separation and alignment, and is prone to over-coupling, making it unsuitable for mobile systems with unknown or loose coupling such as wearables. While ultra-high frequency (UHF) and microwave radiative WPT (0.3-3 GHz) enables meters-long separation between the transmitter and the receiver, free space propagation losses, and rectification inefficiencies, adversely limit the end-to-end efficiency of the WPT link. This work proposes radiative WPT, in the 6.78 MHz license-free band, based on resonant electrically small antennas fabricated using embroidered textile coils, tuned using L-matching networks. The proposed WPT system achieves a stable forward transmission of $mathrm{S}_{21} gt$ – 17 dB and $mathrm{S}_{21} gt$ – 28 dB, independent of coil, separation on the XZ and XY planes respectively, in a $27 mathrm{m}^{3}$ volume space. The presented approach demonstrates the highest WPT-link efficiency, and promises higher end-to-end efficiency, compared to UHF WPT.

This paper presents a spherical wave power generator integrating origami-inspired double-helix multifold electrets for ocean wave energy harvesting. The overall device is self-sustained origami structure, which works as generator as well as suspending spring of central oscillator simultaneously. With ultra-low excitation frequency of 2 Hz, the peak-to-peak output voltage and peak power can be reached up to around 300 V and 18 mW, respectively. It is capable of charging a $10 mu mathrm{F}$ capacitor to 2.5 V within 60 s after connecting a bennet circuit. The output of generator can supply power for 30 LED bulbs and the low-power temperature as well as humidity sensors. Furthermore, with array of folded electret generator units around the central oscillator, the generator is capable of harvesting low-frequency vibration energy in random directions, with a great potential in the field of wave energy collection and power supply for environmental monitoring sensors.

Motivated by recent developments in Wireless Power Transfer (WPT), this work presents a solution for the optimization of a two-stage energy distribution system combining inductive and acoustic power transfer using a clustering algorithm. A network of immobile wireless sensors equipped with acoustic transceivers, storage capacitors and with known cartesian coordinates in a 2D plane is considered. A power delivery vehicle (PDV) with finite energy storage capacity is used to recharge a sensor node’s supercapacitor which then transmits power to neighboring sensors acoustically within range. This work aims to find an optimal charging route for the PDV. The proposed algorithm is a combination of cluster analysis and breadth-first search. A theoretical study was performed, and the simulation results obtained were studied for the long-term failure probability for the proposed energy scheme.
