Measurement of contact stress between clothing and skin using thin and flexible triaxial stress sensor

Autor: Ryuto KAMATA, Kazuhiko SASAGAWA, Kazuhiro FUJISAKI

Publikováno v: Journal of Biomechanical Science and Engineering, Vol 17, Iss 4, Pp 22-00149-22-00149 (2022)

When wearing clothes, one feels pressure, called clothing pressure, and friction. These are considered to be factors of the comfort ableness of wearing clothes. Although the contact pressure on the skin and shear stress due to friction are considered

Demineralization characteristics of cortical bone under voltage application in phosphate-buffered saline

Autor: Keita OSANAI, Kazuhiro FUJISAKI, Fuki OTA, Kazuhiko SASAGAWA, Takeshi MORIWAKI

Publikováno v: Journal of Biomechanical Science and Engineering, Vol 17, Iss 2, Pp 21-00293-21-00293 (2022)

Bone tissue is a composite material consisting of hydroxyapatite and collagen. It is known that bone tissue becomes brittle with age not only because of decreased bone density but also because of excessive apatite deposition in the tissue. Deminerali

Strain analysis of fruit tree branch under large deflection considering flexural deformation characteristics

Autor: Kenta ISHII, Kazuhiro FUJISAKI, Kazuhiko SASAGAWA, Takeshi MORIWAKI

Publikováno v: Journal of Biomechanical Science and Engineering, Vol 17, Iss 1, Pp 21-00092-21-00092 (2021)

Fruit tree branches are deflected with large deformation under bending loads applied owing to fruit weight and environmental burdens such as wind and snow. Stress and strain analyses in large bending deformations of tree branches can prevent tree fai

Demineralization of cortical bone for improvement of Charpy impact fracture characteristics

Autor: Kazuhiro FUJISAKI, Ayumi HASEGAWA, Hiroya YOKOYAMA, Kazuhiko SASAGAWA

Publikováno v: Journal of Biomechanical Science and Engineering, Vol 12, Iss 3, Pp 16-00267-16-00267 (2017)

Bone tissue is a composite structure of apatite particles distributed in collagen fibril matrix on a nano-size scale. Mechanical properties of cortical bone are determined by the apatite-collagen composition. The amount and specific orientation of ap

Damage of single-wall carbon nanotube network structure under electric current loading

Autor: Shunsuke SATO, Kazuhiro FUJISAKI, Kazuhiko SASAGAWA

Publikováno v: Mechanical Engineering Journal, Vol 3, Iss 6, Pp 16-00292-16-00292 (2016)

Carbon nanotubes (CNTs) are highly resistant to deformation, and their electrical characteristics are also resistant to degradation at ambient conditions. The damage mechanisms of CNT loaded under high current density are considered to be the oxidati
