[Problem to be Solved by the Invention] To provide an artificial tissue model that can be more advantageously used in surgical technique training compared to previous artificial tissues, as well as a method of fabricating the same. [Solution] An artificial organ model for surgical technique training comprising two or more fibrous layers 2, 3 layered and bonded to each other so as to be peelable by a surgical technique performed by a surgical technique trainee; the layered and bonded two or more fibrous layers 2, 3 as a whole being saturated with an electroconductive liquid or gel; and two adjacent fibrous layers out of the two or more fibrous layers being formed from different materials or substances or in different colors so as to be recognizable as different membranes by the surgical technique trainee.

An ultrasound probe of the present invention has a piezoelectric element and a backing material disposed on one direction side with respect to the piezoelectric element, the backing material containing heat conductive particles. The backing material has a heat conductivity of 2.0 W/mk or more, and the content of the heat conductive particles is less than 30 vol % based on the total volume of the backing material.

A nasal impression assembly for use in prosthodontics and otolaryngology, wherein the assembly includes detachable components specifically designed for recording precise nasal impressions. The detachable components may include plurality of nasal cones, a pair of injection syringes, and an extra nasal mesh splint, assembled on a horizontal bar. Further a method is provided for measuring/imprinting the impression, by using the assembly, wherein an impression material is brought in contact with extra-nasal and/or intra-nasal structure to imprint its size and/or shape.

A method for preparing a fully soft self-powered vibration sensor mainly uses a laser carbonization technology to prepare a two-dimensional porous carbon electrode with an origami structure, and then transfers the two-dimensional porous carbon electrode to a three-dimensional polydimethylsiloxane (PDMS) cavity through mold transfer; finally, a laser engraving technology is used to create microstructures on surfaces of the porous carbon electrode and a PDMS film. The sensor includes the PDMS film, a liquid metal droplet oscillator, a porous out-of-plane carbon electrode, and a 3D PDMS cavity assembled tightly from top to bottom. The sensor works based on the triboelectric nanogenerator principle, when the sensor is excited by vibrations, contact and triboelectrification at an interface of the liquid metal droplet oscillator and PDMS film charge both objects, making contact surfaces carry stable charges, which allows the movement of the liquid metal droplet oscillator to output current through electrostatic induction.

A fish model to replace the use of live fish in hydroelectric studies is provided. The fish model is cast from ballistic gel to include the density, dimensions, and weight distribution of a selected species of living fish. The fish model is formed by additively manufacturing a mold based on a three-dimensional scan of an actual fish. The mold is then used to mass produce fish models for force measurement testing at various blade speeds, thickness, and impact angles. Each fish model includes a surrogate skin and an internal sensor for strike force measurements. Optional additional sensors include strain gauges, temperature probes, pressure probes, and load sensors, for example.

Disclosed are various embodiments for a dynamic flow apparatus for cardiovascular diagnosis and pre-procedure analysis of individual patients. The dynamic flow apparatus includes a three-dimensional (3D) cardiac model in an enclosed container. The 3D cardiac model can mimic an operation of an actual heart by pumping fluid through the 3D cardiac model and causing the model to expand and contrast. Data obtained from the operation of the 3D model can be used during a surgical procedure of an actual heart of an individual.
