We herein demonstrate micro swimming robots powered by a single-axis magnetic system with controllable mobility and stability. Five distinctive advancements have been achieved: (1) using a single-axis alternating magnetic field to remotely power propeller-style micro swimming robots; (2) controllable moving speed as well as direction for the swimming structure by regulating magnetic field magnitude, frequency, and direction; (3) ultrafast moving speed of 19.1 body length per second under a magnetic field of 1.5 mT; (4) several underwater maneuvering demos including upwards, downwards and stationary motions and movements towards a target location to carry out basic tasks; and (5) attitude stability achieved by the effect of center of pressure over center of mass.

In this paper, inspired by the ossicular chain in human middle ear, a miniature sound pressure amplification structure (SPAS) based on double $10 mu mathrm{m}$-thickness E-shaped steel diaphragms with the corresponding diameters of 15 mm and 3 mm was developed to enhance the sensitivity of diaphragm-type Fabry-Perot (F-P) acoustic sensor. FEM simulation demonstrated the availability of the SPAS in terms of the achieved acoustic field response within a certain frequency range. Then acoustic test showed that the F-P acoustic sensor using a silver diaphragm, adapted with the developed SPAS, achieved a remarkable sensitivity amplification ratio of up to ∼7.6 in the range of 1.5∼2.1 kHz, which can be further widened by optimizing structure dimensions and membrane materials.
为了提高膜片式法布里-珀罗(F-P)声传感器的灵敏度，本文以人类中耳听骨链为灵感，设计了一种基于10 mu mathrm{m}$厚度、直径分别为15 mm和3 mm的双e形钢膜片的微型声压放大结构(SPAS)。有限元仿真结果表明，SPAS在一定频率范围内的声场响应是有效的。声学测试表明，采用银膜片的F-P声传感器在1.5 ~ 2.1 kHz范围内获得了高达7.6的灵敏度放大比，通过优化结构尺寸和膜材料可以进一步扩大。

We present the fabrication and experimental results of a magnetically coupled body motion electrostatic energy harvester chip suitable for a smart contact lens application. The device is designed to be driven by the lateral motion of the eye blinking without any physical contact with the eyelid. The $4times 3 text{mm}^{2}$ harvester generates 486.54 nJ and $6.09 mu mathrm{J}$ of energy per blink and average power of 194.6 nW and $2.44 mu mathrm{W}$ when pre-charged at 3.18 V and 6.27 V, respectively when driven at typical blinking velocity conditions.

The application of high-resolution MEMS strain sensors based on micromechanical resonators fabricated with wafer-level vacuum packaging to the construction of large dynamic range weighing systems is explored. Resonant sensors with sub-nano strain resolution are adopted to build a load cell prototype using a standard aluminum structure normally utilized in commercial weighing systems. A differential strain measurement configuration is implemented with two sensors oriented at 90° between them and fabricated on the same chip for temperature compensation. The load cell equipped with the resonant MEMS sensors shows an excellent dynamic range of 108 dB, effective temperature compensation and good weight measurement reproducibility.

Ovarian cancer is known as a “silent killer” for women because it is difficult to be diagnosed at early stages. The five-year survival rate of early-stage ovarian cancer is 92%, but at the late stages, drops to only 17%. Several tools have been used for ovarian cancer screening; however, the outcome is still not satisfactory. Therefore, there is a great need to develop a new method to screen ovarian cancer precisely. Recently, BRCA1/2 gene mutations were confirmed to be highly associate with the occurrence of ovarian cancer. Patients with these gene mutations are risky of developing it in their lifetime. Liquid biopsy such as cell-free DNA (cfDNA) is an emerging non-invasive technology that brings information about tumors from the blood. Previous studies have found BRCA1/2 gene mutations in cfDNA could serve a potential tool for the screening and risk assessment of ovarian cancer. Therefore, an integrated microfluidic system was developed in this work to extract cfDNA from patients' plasma and BRCA1/2 gene mutations were verified automatically, which can provide clinicians a convenient way for risk assessment.

This paper presents a simple in-house fabrication of a solenoid inductor using 3D printing, selective electroless plating, and electroplating for the inductor, and pressing for a highly laminated metal core. The frame of the solenoid inductor was 3D printed, where the design of the frame has a solenoid trench and ridge for wiring and insulator, respectively. The ridge of the frame was selectively coated with a novolac resin by dipping and rolling. The unique selective electroless plating showed the direct patterning to form a solenoid conductive path that came from the different surface activation. Electroplating to thicken the solenoid wire completes the inductor fabrication. A pressing and stacking of a nickel film form the highly laminated magnetic core for the inductor. A 10-turn solenoid inductor with a wire thickness of was successfully fabricated. An average inductance of 133 nH was measured in air-core condition. A 120 nickel layer cores were integrated into the inductor and showed the boosted inductance of 252 nH. The proposed simple fabrication has a great potential for various RF passive 3D devices including antennas, filters, and waveguides.

This paper reports a new flexible strain sensor using the moiré pattern as the transducing signal, which can be used to map the strain/stress on a planar surface or a curved surface. Different from our previously reported flexible strain sensor based on the nanopore thin film, which uses the reflected optical signal as the transducing signal. This type of strain sensor has the following unique features: one grating (G1) is fabricated on a flexible substrate, the other grating (G2), which has a slightly different pitch, is simply stored in a computer. Images of G1 under different strains/stresses are taken using a smartphone camera. Then moiré patterns are formed by superimposing the images of the two gratings (G1 and G2) in a computer. Finally, the strain/stress is determined by feature extraction of the moiré patterns using image processing.

A new patterning technique for applying the photolithography to the 3D sample is described. A sheet is newly introduced. This sheet has water-soluble polymer of polyvinyl alcohol. On this the photoresist can be spin-coated and patterned using the standard resist spin-coater and the mask aligner. The photoresist with the latent image is pasted on 3D samples. By patterning the resist film before pasting, the limit of Fresnel diffraction can be solved enabling the patterning at the close distance with the photomask. The fine patterns are demonstrated both on convex and concave samples.

We present for the first time a miniature flexible galloping piezoelectric energy harvester that combines a nonlinear aeroelastic energy harvesting structure with an energy extraction circuit employing mechanical synchronous switch harvesting on inductor (mechanical SSHI). Extra stoppers protect the harvester from overload at high wind speed, thus extending the highest working speed from 10 m/s to 13.5 m/s based on wind tunnel tests. The conductive contact on the bluff body and the conductive stoppers further forms a mechanical synchronous switch, used in the SSHI circuit for energy extraction. The maximum power enhancement reaches 221% compared to the design without SSHI, at a low wind speed of 3.6 m/s.

An overview on nanogenerators and energy harvesting systems applied to electrical stimulation of electroactive cells is introduced in this paper. We have already demonstrated the use of ZnO nanostructures and other piezoelectric materials to stimulate osteoblast-like and muscle cells, by means of the local modulation of their membrane potentials with submicron spatial resolution. This stimulation improved proliferation and accelerated differentiation, and seem to be a great tool for the future bioelectronic nanomedicines. Our research is now focused on the development of biocompatible microdevices that integrate smart materials for wireless stimulation of excitable cells, by means of ultrasound or electromagnetic signals.
