摘要： A stretchable piezoelectric thin film, and method of manufacture, an open mesh structure formed by a repeating branching and joining pattern. The thin film is manufactured by slowly lifting amino acid nanofibrils from a water-alcohol biphasic solvent. The film automatically assembles into a truss-like mesh network of amino acid nanofibrils that allows the open meshes to close with narrowed intersection angles between the amino acid nanofibrils. The alcohol molecules of the water-alcohol biphasic solvent preferably bind to the carboxyl groups on the amino acid surfaces thus limiting the growth along the side facets of the amino acid surfaces and promoting growth along the growth front producing a bifurcation in the amino acid biocrystal network.

摘要： The present invention provides a process for the fabrication of a flexible strain and pressure sensor using a synergistic composition of ZnO nanoparticle and graphene nanoplatelets. The substrate used is PDMS, a polymer that imparts the desired properties of flexibility and durability to the sensor. The invention also discloses a simple and facile process of sensor fabrication, wherein the sensing element is embedded in the substrate material, and thereby prevents any deformation or peeling even after repeated stretch/release cycles. The reported flexible sensors can replace the conventional stiff sensors due to their ability to be contoured on curved surfaces, such as body parts. These sensors can find applications in wearable electronics and can have myriad of uses in healthcare monitoring, human-machine interface, electronic skin on prosthetics, and so on.

摘要： Methods, systems, and devices are disclosed for fabricating 3D piezoelectric materials. In one aspect, a method includes photopolymerizing a selected portion of a two dimensional plane in a sample of a photolabile polymer solution containing piezoelectric nanoparticles to form a layer of a piezoelectric material, the photopolymerizing including directing light from a light source based on a pattern design in the selected portion of the photolabile polymer solution; and moving one or both of the sample and the directed light to photopolymerize another selected portion of another two dimensional plane in the sample to form another layer of the piezoelectric material.

摘要： An object of the present invention is to provide a piezoelectric film that has satisfactory durability, is capable of outputting a sound with a high sound pressure, decreases the resistance of an electrode layer, and is capable of suppressing heat generation. The above-described object is achieved by providing the piezoelectric film including a piezoelectric layer containing piezoelectric particles in a matrix that contains a polymer material, electrode layers provided on both surfaces of the piezoelectric layer, and an interlayer provided on at least one side between the piezoelectric layer and the electrode layers, in which the interlayer contains carbon and/or a metal, and a metal atom concentration of 30 to 90 atm % or a carbon atom concentration of 85 to 95 atm % is satisfied.

摘要： A piezoelectric artificial artery can be 3D printed to provide the real-time precise sensing of blood pressure and vessel motion patterns enabling early detection of partial occlusions. An electric-field assisted 3D printing method allows for rapid printing and simultaneously poled complex ferroelectric structures with high fidelity and good piezoelectric performance. The print material consists of ferroelectric potassium sodium niobate (KNN) particles embedded within a ferroelectric polyvinylidene fluoride (PVDF) polymer matrix.
