    　View Summary

    Until now, various types of pressure sensors, including piezoresistive and capacitive types, have been developed using the technology of microelectromechanical systems (MEMSs). However, many of these sensors require complex fabrication processes, making it challenging to form 3-D shapes. In contrast, laser-induced graphene (LIG) shows promise for use in various physical sensors due to its high sensitivity as a piezoresistive material and its simple fabrication process. Polyimide (PI) substrates, commonly used for LIG formation, can be easily grooved and cut by ultraviolet (UV) lasers, allowing for the fabrication of 3-D shapes. In this study, we propose a two-gauge corrugated-type pressure sensor with LIG strain gauges on both the top and back sides of a PI substrate featuring a corrugated structure. The fabrication process involves using a UV laser to fabricate the corrugated structure and a CO2 laser to form the LIG strain gauges. This simple process produced a sensor with dimensions of 10 mm in length, 15 mm in width, and a total thickness of 6 mm. The corrugated sensor deformed 1.8 times more under pressure and demonstrated three times greater sensitivity than the membrane-type PI sensor. This approach is effective for low low-volume production of a large variety of sensors in laboratories because it enables simple design and fabrication using only two types of lasers.

  • Experimental study of the aerodynamic interaction between the forewing and hindwing of a beetle-type ornithopter

    Hidetoshi Takahashi, Kosuke Abe, Tomoyuki Takahata, Isao Shimoyama

    Aerospace (MDPI)  5 ( 3 )  2018.09

    　View Summary

    © 2018 by the authors. Beetles have attracted attention from researchers due to their unique combination of a passively flapping forewing and an actively flapping hindwing during flight. Because the wing loads of beetles are larger than the wing loads of other insects, the mechanism of beetle flight is potentially useful for modeling a small aircraft with a large weight. In this paper, we present a beetle-type ornithopter in which the wings are geometrically and kinematically modeled after an actual beetle. Furthermore, the forewing is designed to be changeable between no-wing, flapping-wing, or fixed-wing configurations. Micro-electro-mechanical systems (MEMS) differential pressure sensors were attached to both the forewing and the hindwing to evaluate the aerodynamic performance during flight. Whether the forewing is configured as a flapping wing or a fixed wing, it generated constant positive differential pressure during forward flight, whereas the differential pressure on the hindwing varied with the flapping motion during forward flight. The experimental results suggest that beetles utilize the forewing for effective vertical force enhancement.

  • Development of a light source with a uniform intensity reinforced by a checkerboard half-mirror positioned within inverse L-shaped UV-LED arrays

    Hidetoshi Takahashi, Isao Shimoyama, Yun Jung Heo

    Applied Physics Express (Japan Society of Applied Physics)  11 ( 6 )  2018.06

    ISSN  1882-0786

    　View Summary

    This paper presents a simple, low-cost, long-lasting UV-LED-based light source with uniform light intensity using a checkerboard half-mirror positioned within inverse L-shaped UV-LED arrays. The light rays from the top UV-LED array passed through the transparent portions of the checkerboard half-mirror, while the light rays from the side UV-LED array were reflected on the remaining opaque portions at right angles. Thus, uniform light intensity was achieved on the bottom area. Using the developed UV-LED light source, we fabricated microstructures with uniform shapes on a large area, thereby showing feasible applications for MEMS fabrication.

  • Scalable fabrication of microneedle arrays via spatially controlled UV exposure

    Hidetoshi Takahashi, Yun Jung Heo, Nobuchika Arakawa, Tesuo Kan, Kiyoshi Matsumoto, Ryuji Kawano, Isao Shimoyama

    MICROSYSTEMS & NANOENGINEERING (NATURE PUBLISHING GROUP)  2 2016.10

    ISSN  2055-7434

    　View Summary

    This paper describes a theoretical estimation of the geometry of negative epoxy-resist microneedles prepared via inclined/rotated ultraviolet (UV) lithography based on spatially controlled UV exposure doses. In comparison with other methods based on UV lithography, the present method can create microneedle structures with high scalability. When negative photoresist is exposed to inclined/rotated UV through circular mask patterns, a three-dimensional, needle-shaped distribution of the exposure dose forms in the irradiated region. Controlling the inclination angles and the exposure dose modifies the photo-polymerized portion of the photoresist, thus allowing the variation of the heights and contours of microneedles formed by using the same mask patterns. In an experimental study, the dimensions of the fabricated needles agreed well with the theoretical predictions for varying inclination angles and exposure doses. These results demonstrate that our theoretical approach can provide a simple route for fabricating microneedles with on-demand geometry. The fabricated microneedles can be used as solid microneedles or as a mold master for dissolving microneedles, thus simplifying the microneedle fabrication process. We envision that this method can improve fabrication accuracy and reduce fabrication cost and time, thereby facilitating the practical applications of microneedle-based drug delivery technology.
