The rub-off test and anterior segment Fourier-domain optical coherence tomography were used to analyze the pigment layer of the lenses. They also completed a rating questionnaire of subjective symptom perception after wearing. Among the four groups, there were significant differences in the ocular surface properties on day 3 (p < 0.05). Most of the ocular surface properties were significantly different between baseline and after being worn on day 1, day 3 and day 7 (p < 0.05), especially for tinted contact lenses with pigment layers on the lens surface. On initial wearing of the tinted contact lenses, contact between pigment layers on the surface of the lens and ocular tissues appeared to irritate the ocular surface more than non-pigment layers on the surface. Pigment-tinted soft contact lenses with lower oxygen permeability may cause worse ischemic signs on the ocular surface. However, the ocular surface adapted gradually and the symptoms decreased after wearing the tinted contact lens.","PeriodicalId":50296,"journal":{"name":"International Journal of Optomechatronics","volume":"14 1","pages":"119 - 130"},"PeriodicalIF":5.5,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15599612.2020.1859657","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43636508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has a wide range of applications in the micro-electro-mechanical system (MEMS), integrated circuit, consumer and power electronics, micro/nanofluidics, etc. Since all devices on the same wafer are sealed and tested at wafer size, it brings lots of benefits compared with the component-level packaging, such as substantial savings in time, materials, and labor. In this review, we firstly introduce the low- and room-temperature Si bonding and their applications in MEMS fabrication. Subsequently, we present applications of the third-generation semiconductor bonding towards optoelectronics. Due to the research in the electro-optical modulation of lithium niobate (LiNbO3) has made revolutionary progress in recent years, we also show the bonding method towards single-crystal LiNbO3 thin-film fabrication. Finally, we set our sights on the bonding of infrared materials, which might be the next research hotspot for the emerging ultrasensitive sensors.","PeriodicalId":50296,"journal":{"name":"International Journal of Optomechatronics","volume":"14 1","pages":"94 - 118"},"PeriodicalIF":5.5,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15599612.2020.1857890","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42635795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultra-long nanowires were used to reduce the junctions between wires, and platinum was to improve the conductivity of the film. The new nanowire-metal-organic composite film possesses excellent conductivity and good transmittance. The composite films containing different silver nanowires exhibit conductivities of as low as 6.9 Ω/sq, and transmittance of 60–80% in the visible light range. The films also showed potentials in practical applications as their resistance is almost linearly temperature-dependent. It also can transfer power to electrical devices.

In this article, a binocular microlens was fabricated by micro-fabrication technology. Then, a smart binocular microlens imaging system is set up. By this system, the near-infrared image with venous distribution and visible light image with actual skin color can be obtained simultaneously. In addition, an improved image fusing algorithm is proposed. The image fusing result shows that the venous details can be clearly shown and the background color of the hand also can be well preserved. Therefore, the proposed scheme can provide more real vein information. As the smart structure of the binocular microlens, the dual-bands microlens imaging system has the potential for miniaturization and could integrate with intelligent glasses for assisting intravenous injection.","PeriodicalId":50296,"journal":{"name":"International Journal of Optomechatronics","volume":"13 1","pages":"30 - 40"},"PeriodicalIF":5.5,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15599612.2019.1634166","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42845432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the conventional adaptive optics system that uses two mirrors to configure as a woofer–tweeter system, the proposed MFDM combines the two mirrors into one by using a two-layer layout design of the actuators. Firstly, based on the governing equations of the magnetic fluid, derived from the principles of conservation of fluid mass and magnetic field, the dynamics model of surface deflection of the MFDM is analyzed in Cartesian coordinates under the boundary conditions of the magnetic field and the kinematic conditions of magnetic fluid. Then, the analytical solutions of the surface movement of the mirror subject to the applied currents in the electromagnetic coils are obtained by properly separating the variables with truncated model numbers. Finally, the experimental results based on a fabricated prototype square MFDM show the effectiveness of modeling and the correction performance of the mirror for the full-order aberrations.","PeriodicalId":50296,"journal":{"name":"International Journal of Optomechatronics","volume":"13 1","pages":"1 - 17"},"PeriodicalIF":5.5,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15599612.2019.1588930","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44178643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
