This study explores the impact of a micro dry-etching technique on strain sensing based on multimode interference in a perfluorinated polymer optical fiber (POF). We demonstrate a drastic shift in strain sensitivity, from+ 34 nm/% in a non-etched POF to− 981 nm/% in the etched POF. This notable change may be attributed to the excitation of the axially asymmetrical modes in the etched POF, which is confirmed through simulation on the stress distribution across the core. In addition, a critical wavelength for multimode interference is observed in a POF.

Nickel-boron alloys are prepared by an electrodeposition method. The as-deposited nickel-boron alloy is then annealed at 250 °C and 400 °C for 4 h. Their mechanical strengths and specimen size effects on the strength are evaluated by micro-compression test using pillar-type micro-specimens fabricated by focused ion beam system. In all as-deposited and annealed specimens, a smaller-is-stronger specimen size effect is confirmed. The compressive strength of the nickel-boron alloys reaches a maximum of 5.79 GPa with the smallest specimen size in this work.

This paper reports an equivalent circuit model of self‐assembled electret (SAE) micro‐electro‐mechanical systems (MEMS) vibrational energy harvesters (VEHs). For the first time, a detailed equivalent circuit model of the SAE‐MEMS VEH has been implemented on a circuit simulator, considering the device energy diagram. The implemented equivalent circuit model allows analysis of the relationship between output current and SAE properties, device structures, and electrode materials. The validity of the model is confirmed by comparing the measurement and simulation results.

Alloy electrodeposition of Ni-Co alloys is known to show an anomalous codeposition behavior, which the concentration of cobalt in the deposited alloy is higher than the concentration of cobalt ions in the electrolyte. In this study, the cobalt content in the alloy is increased from 30 at% to 60 at% through introduction of bromide ions into a sulfamate bath, while addition of chloride ions does not give any significant influences to the alloy. The bromide ions are found to promote the reduction of cobalt ions but inhibit the reduction of nickel ions. Effects of the pH are also investigated to provide possible explanation to the phenomenon observed, and the anomalous codeposition behavior becomes more obvious in a more acidic electrolyte.

Energy harvesting [1] is expected to be a self-powering technology for small wireless sensor nodes in the next generation Internet-of-Things (IoT). In particular, small vibrational energy harvesters (VEHs) based on micro-electro-mechanical systems (MEMS) technology, which are battery-free and can generate electricity even at night or in the dark, are being investigated worldwide for next-generation power sources for small wireless IoT nodes [2,3]. Electrostatic MEMS VEHs, which use semi-permanent charge-holding dielectrics called "electrets," are useful for power generation using environmental vibrations because they have a higher output power density at lower frequencies than other methods [4]. Further miniaturization, higher performance, and higher productivity will be required to use electret-type MEMS VEHs as power sources for compact wireless IoT nodes and other devices. Although the integration of …

In this paper, we present the observation results of the surface potential of micropatterned thick (> 1 μm) self-assembled electrets (SAEs) for MEMS vibrational energy harvesters (VEHs). To evaluate the surface potential of micropatterned SAEs, we propose and develop test devices with removable through-hole substrates corresponding to the moving electrodes of SAE-MEMS VEHs. In this study, SAEs are deposited simultaneously on two test devices with different through-hole spacings and on a reference flat substrate using the same vacuum evaporation process. The surface potential of SAEs is proportional to the film thickness, and when the film thickness of the SAE deposited on the flat substrate is 4.48 μm, the surface potential exceeds 200 V. At this time, in a test device where the average thickness of micropatterned SAEs is 3.08 μm, the measured surface potential is 68 V. In addition, it is experimentally …

Nickel–cobalt alloys were prepared by alloy electrodeposition with a sulfamate bath, and the mechanical properties on the micro-scale were evaluated for the application as micro-components in miniaturized electronic devices. Nickel bromide and a commercially available surface brightener were used as the additives. The cobalt content increased from 21.5 to 60.1 at.% after addition of nickel bromide into the bath, and the grain size refined from 21.1 to 13.2 nm when the surface brightener was used. The mechanical properties on the micro-scale were evaluated by micro-compression test using micro-pillar type specimens fabricated by a focused ion beam system to take the sample size effect into consideration. The yield strength of the nickel–cobalt alloy having an average grain size at 13.9 nm and cobalt content of 66.6 at.% reached 2.37 GPa, revealing influences from the sample size, grain boundary strengthening, and solid solution strengthening effects.

This paper reports the first direct measurement results of the surface potential of micro-patterned self-assembled electrets (SAEs) for microelectromechanical systems vibrational energy harvester applications. We have developed an evaluation chip that utilizes a removable shadow mask with through-holes to realize SAE micro-patterning during SAE evaporation. A Kelvin probe is used to measure the surface potential of the micro-patterned SAEs. The surface potential of the micro-patterned SAEs with the average thickness of 65 nm was found to be 2099 mV, which is in the same order of magnitude as the surface potential estimated from the average thickness of the SAEs.

Ni–B alloy films are prepared by electrodeposition with a Watt's bath-based electrolyte. The B content decreases from 14.3 at% to 2.8 at% as the current density increases from 1 A dm− 2 to 4 A dm− 2. For applications in miniaturized electronics, the micro-scale mechanical property is evaluated by micro-compression test using micro-pillar type specimens. As-deposited Ni–B alloy films exhibit high mechanical strengths and ductility. The Ni–B alloy films are heat treated to evaluate the thermal stability. After the heat treatment, strengthening and formation of an intermetallic compound, Ni 3 B, are confirmed. The deformation behavior of the micro-pillars changes from ductile to brittle after the 250 C heat treatment, and the compressive strength of the Ni–B alloy film having the B content of 2.8 at% reaches 5.52 GPa due to the precipitation strengthening mechanism by the Ni 3 B.

In this paper, we present demonstration results for a contactless electrostatic vibration energy harvester (E-VEH) using electric double layer electrets (EDLEs). We, for the first time, utilize the surface potential of EDLEs to generate electrostatic induction currents for contactless VEH devices. A proof-of-concept in-plane EDLE E-VEH is designed and developed using precision machining technology. An array of EDLEs is developed and the surface potential is measured under atmospheric conditions and found to be− 1 V on average. The proposed contactless energy harvesting method using the electrostatic induction of EDLEs is successfully demonstrated by performing vibration experiments under atmospheric conditions. We confirm a typical output current of about 2 pA (peak-to-peak) with a load resistance of 1 MΩ at an input acceleration of 1 G with a frequency of 155 Hz. The proposed vibration energy harvesting …

This paper presents a methodology to extend the working bandwidth of vibration energy harvesters (VEHs) by using a voltage-boost rectifier (VBR) circuit. The VBR circuit rectifies small ac voltages of MEMS VEHs and boosts them to a dc voltage sufficient for the operation of the subsequent circuitry. The proposed system using the VBR circuit can work regardless of the VEH type. Also, the VBR circuit can be monolithically integrated with CMOS LSI without using other external components. The developed VBR circuit is experimentally evaluated using a MEMS VEH and successfully delivers boosted dc voltages even when the input ac amplitude is below 0.4 V in the frequency range (< 1 kHz) of environmental vibrations. We confirm that the working bandwidth can be increased by employing the VBR circuit compared with the use of conventional diode rectification.

Effects of current density on micro-mechanical properties of electrodeposited gold were evaluated by micro-compression test. Three gold films were electrodeposited at 20 A/m2, 50 A/m2 and 100 A/m2. The average grain sizes were analyzed by XRD. The specimens used in the micro-compression test were micro-pillars having a square cross-section and the long-side parallel to the Au/electrolyte interface fabricated by focused ion beam. Three sizes of the cross-section were prepared, which were 8 μm × 8 μm, 10 μm × 10 μm and 15 μm × 15 μm, and the height was kept at twice of one side of the cross-section. The micro-pillars all showed high yield strengths ranged from 400 MPa to 650 MPa, because of the micro-scale sample size by the sample size effect and the nano-scale average grain size by the grain boundary strengthening. In addition, the largest sample size effect was observed in micro-pillars fabricated …

Electret-based microelectromechanical system (MEMS) vibratory energy harvesting is a key technology for converting the mechanical energy of environmental vibrations into electricity. Unfortunately, conventional electret charging methods generally rely on high-voltage and high-temperature processes that present limitations to MEMS design and production. Here, we show a MEMS post-processed self-assembled electret (SAE) that enables the integration of electrets with MEMS vibratory devices via evaporation as a post-MEMS process. Owing to the spontaneous orientation of polar molecules, the surface potential of the SAE can build up at room temperature in a microscopic region without charging processes, which enhances the design and fabrication flexibility of electret-based MEMS energy harvesters. We develop a MEMS vibratory device followed by post-processing the SAE and confirm induced electrical …

This paper reports demonstration results of a non-contact type vibration energy harvester (VEH) with electric double layer (EDL) electrets. The surface potential of EDL electrets is, for the first time, utilized to generate induced electrical currents by input vibration. A proof-of-concept in-plane VEH is designed and developed by precision machining processes. The average surface potential of the developed EDL electret is experimentally obtained to be about −2 V. The VEH evaluation results successfully demonstrate the proposed non-contact type power generation, where we confirm a typical output current of about 40 nA (peak-to-peak) with the load resistance of 1 MΩ at the input acceleration of 1 G (1 G = 9.8 m/s 2 ) with the frequency of 155 Hz. The proposed power generation mechanism would contribute to expanding the usage environment of VEHs with EDL electrets.

Ti/Au multi-layered micro-cantilevers with complex three-dimensional structures used as micro-components in micro-electromechanical systems (MEMS) sensors were prepared by lithography and electrodeposition, and the effective Young’s modulus was evaluated by the resonance frequency method and finite element method simulation. Effects of the constraint condition at the fixed-end of the micro-cantilever and the temperature dependency of the effective Young’s modulus were studied. Three types of the constraint at the fixed-end were prepared, which were normal type (constraining only bottom surface of the fixed-end), block type (constraining both top and bottom surfaces), and bridge type (top surfaces covering with a bridge-like structure). The temperature dependency test was conducted in a temperature range from 150 to 300 °C in a vacuum chamber. An increase in the effective Young’s modulus was observed as the constraint condition became more rigid, and the effective Young’s modulus merely changed as the temperature varied from room temperature to 300 °C.
