  • Proposal of a three-stage hair structure imitating the sole of gecko foot and its fabrication by UV nanoimprinting

     View Summary

    © 2020 Elsevier Inc. In order to apply UV nanoimprinting method to fabricating fine hairs, which imitates those on sole of a gecko's foot, the shape of hair was designed as straight, making it easy to be released from the mold. The length of hairs which branch off at the tip was designed to be short, preventing them from aggregating. Under these restrictions, considering the asperities due to roughness of objective surface, a three-stage hair structure comprising a root hair, intermediate hairs, and tip hairs was proposed instead of the two-stage hair structure comprising a seta and spatulae of the gecko, so that the tip hairs can easily come into contact with the surface of asperities. A high-precision 3D stereo-lithography was used to fabricate a master consisting of a base and the hairs. A polydimethylsiloxane (PDMS) mold was obtained by transferring this master to PDMS. By performing UV nanoimprinting using this mold, we succeeded in fabricating fine hairs made of photo-curable resin. This method has the advantage that the three-stage hairs can be fabricated by single nanoimprint due to 3D lithography capable of realizing the master of complicated structure with high aspect ratio, i.e., it is not necessary to nanoimprint twice on the root and the tip separately. It was confirmed that the fine hair fabricated by UV nanoimprinting showed the adhesive force.

  • Twice Stretched Fabrication of Polylactic Acid Microneedle Arrays Using Drawing Lithography

    INTERNATIONAL JOURNAL OF PRECISION ENGINEERING AND MANUFACTURING   21 ( 10 ) 1933 - 1942  2020.10  [Refereed]

    Authorship:Lead author

     View Summary

    A biodegradable poly-lactic acid (PLA) microneedle array composed of needles with a maximum length of 3 mm and an aspect ratio of up to approximately 18 was fabricated by drawing lithography. In the proposed fabrication method, the melted polymer is stretched twice. The approximate length is set in the first stretch, and the tip is sharpened in the second stretch. In the first stretch, by changing the thickness of the PLA sheet, PLA pillars with various lengths are fabricated. By defining the initial length of the needle, it is possible to set a wide range of aspect ratios and lengths. In the second stretch, it is possible to control the final aspect ratio and length of the needle, as well as the shape of its tip by changing the temperature and stretch speed of the PLA pillars. Finally, it was confirmed that the needle can pierce the surface of artificial skin and porcine skin.

  • Fabrication of hyaluronic acid hollow microneedle array

    JAPANESE JOURNAL OF APPLIED PHYSICS   59  2020.06  [Refereed]

    Authorship:Lead author

     View Summary

    A hollow microneedles array using biodegradable hyaluronic acid as the material for the microneedle array was fabricated. We proposed a method in which gelatinous hyaluronic acid was affixed to a core and then released after drying. A polylactic acid which has high tensile strength and high affinity for hyaluronic acid was used as the core material. Using this method, we succeeded at fabricating a highly safe hollow microneedle array. An opening was formed in the needle tip by coating the tip of the core with a hydrophobic UV curable resin. The diameter of the needle tip could be reduced by using a conical core, and the needle tip was sharpened by cutting it with a femtosecond laser. The mechanical strength of hyaluronic acid hollow microneedle was evaluated using the surface of artificial skin. (C) 2020 The Japan Society of Applied Physics

  • Fabrication of microneedle using poly lactic acid sheets by thermal nanoimprint

     View Summary

    A biodegradable PLA (poly-lactic acid) microneedle having high aspect ratio of over 10, e.g., 100 pm in diameter and 1,000 pm (1 mm) in length, was successfully fabricated using thermal nanoimprint method first in the world. First, optimal conditions for fabricating a conical shape, which is assuming a microneedle tip, were preliminarily investigated. Both in vacuum and under atmospheric pressure, pressure of 20 MPa and temperature of 160 degrees C were necessary. Next, fabrication of a long microneedle was investigated. As compared to the conical shape, higher pressure of 25 MPa and higher temperature of 166 degrees C were required. By adjusting the releasing temperature around 98 degrees C, fabrication of a long microneedle having a smooth surface and no deformation, e.g., no bending, was successfully achieved. It was confirmed that the needle surely can puncture the skin and blood vessel of a mouse.

  • Effect of salt concentration on permeation performance in hollow fiber type PRO membrane module

    MECHANICAL ENGINEERING JOURNAL   4 ( 3 )  2017  [Refereed]

     View Summary

    The new sustainable power generation technique which can convert the salinity gradient energy to the hydroelectric energy is expected. This technique is called Pressure Retarded Osmosis (PRO). Clarification of the relationship between the performance of the PRO module and permeation characteristics is important. It's already known that increase of salt concentration can increase the permeation flux through the membrane. As the conventional researches, the effects of increase of fresh water concentration and concentration polarization have evaluated. In this research, relationship between the salt concentration and membrane module is focused. The effects of fresh water dissipation and flow state of salt water in hollow fiber membrane module as new factors are researched with experiment and numerical simulation. As result, in the case of low salt concentration, permeation is not caused sufficiently in module. On the other hand, in the case of high salt concentration, very low permeation flux area exists extensively, and the effects of concentration polarization and fresh water dissipation are relatively large. Therefore salt water flow rate and module shape should be changed for each salt concentration.

  • Permeation characteristics of fresh water in hollow fiber membrane module for pressure retarded osmosis

    Shingo Terashima, Hidechito Hayashi, Tetsuya Okumura, Tetsuro Ueyama, Kei Matsuyama, Hideyuki Sakai

    MECHANICAL ENGINEERING JOURNAL   3 ( 6 )  2016  [Refereed]

    Authorship:Lead author

     View Summary

    Pressure Retarded Osmosis (PRO) is expected to the new power generation system. The performance of the PRO module is closely relating to the permeation characteristics. In this paper, when fresh water flow rate is changed, 4 factors related to the reduction of permeation flow rate are researched with experiment. These 4 factors are concentration of solute in fresh water, salt leakage, concentration polarization, and dissipation of fresh water. The characteristics of the fresh water flow and permeation are studied for the hollow fiber membrane module used in PRO system. It is cleared that the dissipation of fresh water and the concentration polarization in hollow fiber largely influence to the reduction of permeation flow rate in the case of the low fresh water flow rate. Concentration of solute in fresh water, salt leakage influence to the reduction of permeation flow rate in the case of high fresh water flow rate.

     View Summary

    Forward Osmosis (FO) is recently paied attention to preprocessing of the Reverse Osmosis (RO). It can reduce the input power of RO plant. It is required to reduce the salt concentration at outlet and increase the permeation flow rate. In this paper, the characteristics of the fresh water flow and permeation are studied for the hollow fiber membrane module used in FO system. It is cleared that the disappearance of fresh water and the concentration polarization in hollow fiber largely influence to the reduction of permeation flow rate in the case of the low fresh water flow rate. Concentration of fresh water and the leakage of salt influence to the reduction of permeation flow rate in the case of high fresh water flow rate.
