摘要： A method of additive manufacturing may include disposing a layer of a powder material on a surface of a build platform of an additive manufacturing apparatus. The method may also include placing a compaction platform comprising one or more transducers in contact with an upper surface of the layer of the powder material. The method may additionally include activating at least one transducer of one or more transducers of the compaction platform of the compactor to densify a portion of the layer of the powder material below the at least one transducer while at least the weight of the compaction platform applies a normal force to the layer of the powder material. Related systems for densifying additively manufactured components are also described.

摘要： A self-powered sensing system. The sensing system may include a power generator at least partially disposed in a diamond composite heat sink configured to harvest energy from a hazardous environment. The sensing system may further include an energy storage device operatively coupled to the power generator. The sensing system may also include at least one sensor operatively coupled to the energy storage device and a sensor antenna operatively coupled to the at least one sensor. The sensor antenna may be configured to transmit information collected from the at least one sensor to an operation system. The at least one sensor may include a resonance tube having a three-dimensional lattice structure.

摘要： Acoustic impedance matching devices and related methods are disclosed. An acoustic impedance matching device includes a first face for facing an acoustic transducer, a second face opposite the first face, and a lattice structure between the first face and the second face. The second is face curved to at least substantially conformally engage an inner surface of a tubing. An effective acoustic impedance of the lattice structure substantially matches a transducer acoustic impedance of the acoustic transducer to a tubing acoustic impedance of the tubing. A material acoustic impedance of a material of the lattice structure is greater than the effective acoustic impedance. A method of manufacturing an acoustic impedance matching device includes providing, to an additive manufacturing apparatus, a digital design defining the lattice structure, providing an additive manufacturing material to a material intake of the additive manufacturing apparatus, and manufacturing the lattice structure using the additive manufacturing material.

摘要： A method of designing and forming at least one element of an acoustic transducer. The method includes receiving one or more required operating parameters of the at least one element of the acoustic transducer for an application, iteratively modeling and simulating performance of one or more materials to utilize within the at least one element of the acoustic transducer, iteratively modeling and simulating performance of one or more structures to utilize within the at least one element of the acoustic transducer, identifying at least one material and at least one structure that exhibit predicted performance that at least achieves the one or more required operating parameters of the at least one element of the acoustic transducer for the application, outputting a design of the at least one element of the acoustic transducer, and forming the at least one element of the acoustic transducer via one or more additive manufacturing processes.

摘要： An enclosure for a thermoelectric generator may include bonded particles of an allotrope of carbon, such as diamond particles, graphene particles, and/or carbon nanotube particles. A thermoelectric generator system may include one or more thermoelectric generators positioned at least partially within the enclosure. The enclosure may be manufactured using an additive manufacturing process which may include providing particles of an allotrope of carbon, and selectively binding a portion of the particles with a binder material. The bound particles may then be sintered to form the enclosure.

摘要： A method of forming a piezoelectric device may include depositing a sol-gel film over a substrate and curing the sol-gel film by impinging light onto an exposed surface of the sol-gel film to form a piezoelectric ceramic element. The method may produce a piezoelectric composite material including at least two piezoelectric ceramic pillars over the substrate. The at least two piezoelectric pillars may include at least one layer. The at least one layer having a gradient density, such that a first portion of the at least one layer proximate the substrate has a density lower than a second portion that is located a greater distance from the substrate than the first portion. The piezoelectric composite material may further include a resin separating the at least two piezoelectric ceramic pillars.
