A printing process of high resolution, preferably medical, devices with complex geometries is described, comprising the steps of: printing a model (1) with a three-dimensional printing method by using a three-dimensional printer; said model (1) positive reproducing the medical device (10) to be made; - said model (1) being printed of a first water-soluble polymer (2) or aqueous solutions; covering said model (1) with a layer of material (3) insoluble to a solution able to dissolve said first soluble polymer (2); said covering step making a shell of solid mold (7) provided with a surface comprising empty interstitial spots; - infiltrating an amount of water or aqueous solution into said solid mold through said empty interstitial spots so that to dissolve said model (1) and to make a mold cavity (8) negative reproducing said model (1); - infiltrating into the mold

The invention relates to a sensor element for detecting at least one analyte in a body fluid or in a body tissue, particularly for determining at least one metabolite concentration in a body fluid. The sensor element comprises an implantable, one-piece shaped body, which comprises a sensor end and a coupling end. The shaped body comprises, in the area of the sensor end, at least one sensor area, which comprises at least one sensor material. The sensor material changes at least one optically measurable property in the presence of the analyte. The shaped body also has at least one optically transparent coupling part, which is designed to transmit electromagnetic radiation in at least one spectral range between the sensor area and the coupling end. In the sensor area, the shaped body has at least one optically transparent matrix material, and the analyte can at least partially diffuse through the matrix material to the sensor material. The sensor material is embedded in the matrix material. The coupling part is formed at least partially by the matrix material.

An embodiment can provide a polyamide-imide film and a method for producing same, the film comprising a polyamide-imide polymer formed by polymerizing an aromatic diamine compound, an aromatic dianhydride compound and a dicarbonyl compound, wherein, in an XRD graph with a section in which 2θ=8° to 32° as a baseline, the film shows a peak area of 50% or above around 2θ=23° with respect to a peak area seen around 2θ=15°.

According to one embodiment, a gripping tool includes a gripper. The gripper is flexible and includes a first portion contacting a workpiece, a second portion opposing the first portion, and a granular material provided between the first portion and the second portion. The first portion includes a concave portion and a convex portion. The concave portion is recessed in a first direction. The first direction is from the first portion toward the second portion The convex portion is provided around the concave portion and protrudes in a second direction. The second direction is the reverse of the first direction. The concave portion has a groove having a ring configuration recessed outward from a center of the gripper.

A composite material molding method is provided for forming a composite material. The molding includes disposing a reinforcing base material in a cavity inside an openable and closable mold, injecting resin into the cavity in a state in which a clamping pressure is exerted on the mold and curing the resin. When injecting the resin into the cavity, the injection pressure of the resin is adjusted between a first pressure that is higher than the clamping pressure and a second pressure that is lower than the clamping pressure, and the injection pressure of the resin is lowered from the pressure that is higher than the clamping pressure to the pressure that is lower than the clamping pressure at least once. The resin is thereby injected such that the pressure inside the cavity does not exceed the clamping pressure from the start of injection to the end of injection of the resin.

A method of producing a transdermal absorption sheet includes: filling needle-like recessed portions on a mold having the needle-like recessed portions with a polymer solution; drying the filled polymer solution to form a polymer layer; and peeling off the polymer layer, wherein, in drying the polymer solution, low rate drying conditions are set in a concentration range in which an average solid content concentration of the polymer solution is 70 wt % to 80 wt %. When a constant drying rate of water is used as an index, in the concentration range in which the average solid content concentration of the polymer solution is 70 wt % to 80 wt %, and the constant drying rate is lower than a maximum value of a constant drying rate under a drying condition where the average solid content concentration of the polymer solution is less than 70 wt % and more than 80 wt %.
