Adhesion method between titanium material and bio-soft tissue, fixing sensor to living body, deformation assisting method for bio-soft tissue, perforation-sealing method for bio-soft tissue, reinforcement method for bio-soft tissue, adhesive for bio-soft tissue, implantable sensor , Bio-soft tissue deformation aid, bio-soft tissue perforation sealant, and bio-soft tissue reinforcement
PROBLEM TO BE SOLVED: To easily bond a solid member to a living soft tissue in a short time. SOLUTION: The surface of a titanium material having a nano-to-micrometer-sized uneven structure formed on the surface by performing any chemical treatment of acid treatment, alkali treatment, and alkali acid treatment, and a biological soft tissue. By contacting, the titanium material and the biosoft tissue are adhered. The chemical treatment may include acid treatment with hydrochloric acid solution, nitric acid solution, sulfuric acid solution, hydrogen peroxide solution, hydrofluoric acid, hydrobromic acid or a mixture thereof. Alternatively, the chemical treatment may include alkali treatment with a sodium hydroxide solution, a potassium hydroxide solution, a sodium hypochlorite solution or a mixture thereof.
