In this paper, we measured bulk modulus of microfluidics using bulk acoustic wave (BAW) MEMS sensors. The 2.5 GHz resonant sensor interacted with fluids by longitudinal bulk acoustic waves. Measurement experiments were carried out on 1 pL glycerol-water sample droplets, and the results were compared with theoretical models. We showed that the longitudinal acoustic wave sensors are sensitive to bulk modulus of microfluidics (sensitivity of 12.42 MHzm2N−1). We also validated that the sensors are insensitive to viscosity, which is another important liquid property usually measured by shear acoustic wave sensors.
本文采用体声波(BAW) MEMS传感器测量微流体的体模量。2.5 GHz谐振式传感器通过纵向体声波与流体相互作用。对1 pL甘油-水样液滴进行了测量实验,并与理论模型进行了比较。结果表明,纵向声波传感器对微流体的体积模量非常敏感(灵敏度为12.42 MHzm2N−1)。我们还验证了传感器对粘度不敏感,这是剪切声波传感器通常测量的另一个重要的液体特性。

An experiment-based model, which differs from the current curve fitting and particle motion models, is presented for simulating the Focused Ion Beam (FIB) process and guiding the scan strategy and parameter design. This approach applies Gaussian function fitting on both etching and deposition, and builds an expectation difference function to describe the distance changes between the distribution centers of the etching and the redeposition, which shows good performance in solving the redeposition effect and its attenuation. Through a series of basic experiments, we optimize the model parameters and demonstrate that this method can effectively simulate the dynamic process of FIB sputtering. This model and the optimized parameters are further applied to the scan strategy and process parameter optimization for the complex Micro/Nano-structure realizations using FIB.

For the first time, it is experimentally validated that the output voltage from series-connected piezoelectric elements on MEMS structure can be multiplied without degradation. The output voltage has been degraded for conventional devices (piezoelectric voltage-output sensors) based on the series-connected piezoelectric elements because of parasitic capacitances. The elimination of the parasitic capacitance by using not Si but polymer for structural material achieves output voltage multiplication.
首次通过实验验证了MEMS结构上串联压电元件的输出电压可以成倍增加而不降低。由于寄生电容的存在,基于压电元件串联的传统器件(压电电压输出传感器)的输出电压出现了下降。采用聚合物而非硅作为结构材料消除了寄生电容,实现了输出电压倍增。

This paper reports on the first demonstration of an infrared (IR) wireless sensor node (WSN) with near-zero standby power consumption. The prototype presented here employs a plasmonically-enhanced micromechanical photoswitch (PMP) that exploits the energy contained in the impinging IR spectral band of interest itself, to perform passive sensing and digitizing functions. The palm-sized IR WSN demonstrated in this work comprises a vacuum-packaged PMP (IR power threshold ∼284 nW, lithographically-defined IR absorptance: ∼89% at 4.6 μm, 0.75 μm bandwidth) connected to a CMOS load-switch which wakes up a coin battery-powered sub 1-GHz wireless microcontroller to transmit data when the IR signal of interest is detected. The standby power consumption for the IR WSN was measured to be just ∼2.6 nW: a >1900X improvement over state-of-the-art pyroelectric IR WSNs, while offering integrated spectral-selectivity. This work represents the first demonstration of an OFF-but-alert WSN that awakens only in the presence of a signal of interest, resulting in near-unlimited battery-life when deployed to detect infrequent but time-critical events.
本文报道了一种待机功耗接近零的红外(IR)无线传感器节点(WSN)的首次演示。这里展示的原型采用了等离子体增强的微机械光开关(PMP),利用感兴趣的撞击红外光谱带本身所含的能量来执行被动传感和数字化功能。本研究中展示的手掌大小的红外WSN包括一个真空封装的PMP(红外功率阈值~ 284 nW,光刻定义的红外吸收率:~ 89%,4.6 μm, 0.75 μm带宽),连接到CMOS负载开关,当检测到感兴趣的红外信号时,该开关唤醒硬币电池供电的sub - 1 ghz无线微控制器来传输数据。红外WSN的待机功耗仅为~ 2.6 nW:比最先进的热热电红外WSN提高了1900X,同时提供了集成的光谱选择性。这项工作首次展示了一种off -but- alarm WSN,该WSN仅在存在感兴趣的信号时才会唤醒,当部署到检测不频繁但时间关键的事件时,会产生近乎无限的电池寿命。

High performance applications such as the detection of seismic activity or structural health monitoring require sensors with low resonance frequencies. For micro-electro-mechanical-system (MEMS) accelero-meters and vibration sensors it is crucial to lower the resonance frequency in order to increase its sensitivity or bandwidth. In contrast to commercial devices which exhibit resonance frequencies of more than 500 Hz, we present extremely sensitive, optically read-out devices with resonances down to 45 Hz. This low resonance frequency was mainly achieved by fabricating the complete seismic mass from one single crystal silicon block. Compared to previously reported work the resonance frequency could be lowered from over 940 Hz down to 45 Hz while the resolution was massively increased from 7.6 μg/sqrt(Hz) to 1.17 μg/sqrt(Hz) (@4 Hz).
高性能应用,如地震活动检测或结构健康监测,需要低共振频率的传感器。对于微机电系统(MEMS)加速度计和振动传感器来说,降低谐振频率以提高其灵敏度或带宽是至关重要的。与显示共振频率超过500 Hz的商用设备相比,我们提出了谐振频率低至45 Hz的极其敏感的光学读出设备。这种低共振频率主要是通过用一个单晶硅块制造完整的地震质量来实现的。与先前报道的工作相比,共振频率可以从超过940 Hz降低到45 Hz,而分辨率从7.6 μg/sqrt(Hz)大幅增加到1.17 μg/sqrt(Hz) (@4 Hz)。

We demonstrate a novel tunable thermo-triboelectric energy harvesting system for the use of human body heat as an energy source of self-powered applications. Magneto-Thermoelectric Generator platforms have potential to provide new approach for thermal energy harvesting. The concept of MTG stems from a radically different technology developed by UCLA/KPU research community for harvesting of thermal energy. The proposed approach can convert thermal energy from human body heat into electricity by pairing triboelectric effect and MTG concept. The focus of this research is to determine the technical feasibility of presented technology platform for the consistent and efficient power performance using low temperature gradient from human body heat, including experimental characterization of a prototype fabricated.

This paper reports on a MEMS force plate for measurement of total ground reaction force (GRF) of an ant during running. To achieve both high force sensitivity and ensuring area for ant running with several steps, the MEMS force plate consisted of two cantilever chips and one plate which were fabricated separately. The force plate was designed to measure vertical directional force with the force resolution under 0.5 μΝ. Using the fabricated MEMS force plate, we measured the GRF of Messor aciculatus. The results showed that the fluctuation of the ground reaction force was 3.7 % to the body weight of the ant.

This paper reports experimental investigation of damping factors for 20% Scandium-doped Aluminum Nitride (ScAlN) laterally vibrating resonators (LVRs). ScAlN films for LVRs are very promising since they enable greater electromechanical coupling (kt2) than undoped AlN films (∼ 2X for 20% doping), but have generally exhibited lower quality factors (Qs) [1,2]. This work is the first to study what damping factors impact the performance of these devices and provide preliminary design guidelines to attain high Qs. Different ScAlN LVR geometries are analyzed and devices tested in air, under vacuum, and at cryogenic temperatures (11 K). Anchor losses and thermoelastic damping (TED) are evaluated and compared to AlN LVRs. Similarities in thermal scaling of Qs in ScAlN resonators indicate that the source of TED is similar to AlN devices.
本文报道了20%掺钪氮化铝(ScAlN)横向振动谐振器(LVRs)阻尼因子的实验研究。用于lvr的ScAlN薄膜非常有前途,因为它们比未掺杂的AlN薄膜(掺杂20%时为~ 2X)具有更大的机电耦合(kt2),但通常表现出较低的质量因子(Qs)[1,2]。这项工作首次研究了阻尼因素对这些器件性能的影响,并提供了获得高q的初步设计指南。分析了不同的ScAlN LVR几何形状,并在空气、真空和低温(11 K)下对设备进行了测试,评估了锚定损失和热弹性阻尼(TED),并与AlN LVR进行了比较。在ScAlN谐振器中Qs热标度的相似性表明TED的源与AlN器件相似。

This paper presents a novel interdigital transducers (IDTs) actuated AlN microcantilever humidity sensor coated with graphene oxide (GO) thin film as sensing layer. Utilizing the IDTs, the microcantilever can operate at very high resonant mode to achieve significant high sensitivity. Compared with the normal electrodes actuated microcantilever sensor with the same size, the sensitivity of the IDTs actuated microcantilever sensor is increased by more than 10 times. Moreover, very little hysteresis, excellent short term repeatability, fast response and short recovery times (less than 10 s) of the sensors are obtained.

Our device is 2.4–9.4 times more stretchable than the state-of-the-art stretchable supercapacitors using the Accordion construct, and enjoys 4 times higher areal-coverage than the previously reported stretchable supercapacitors with the Island-Bridge construct. The Kirigami-inspired design is the key to both high stretchability and high areal-coverage. We envision our stretchable micro-supercapacitor patch (and other power-supply microdevices with a similar design) to be highly desirable in future flexible, stretchable, and wearable systems.
我们提出了一种具有极高可拉伸性的微型超级电容器贴片(可逆拉伸性>282.5%,电容保留变化<2%),具有高面积覆盖率的功能电子元件(76.2%)。我们的设备比使用Accordion结构的最先进的可拉伸超级电容器的可拉伸性高2.4-9.4倍,并且比先前报道的使用Island-Bridge结构的可拉伸超级电容器的面积覆盖率高4倍。kirigami风格的设计是高拉伸性和高覆盖面积的关键。我们设想我们的可拉伸微型超级电容器贴片(以及其他具有类似设计的电源微型设备)在未来的柔性,可拉伸和可穿戴系统中非常理想。
