Abstract: A pressure distribution mapping system includes a flexible M×N textile-based pressure sensor array. with first and second electrode textile layers and a piezoresistive fabric layer with a sheet resistance of at least 60 k-ohm/square positioned between the first and second electrode textile layers. Individual pressure sensors are formed by an intersection between a row electrically-conductive path and a column electrically-conductive path along with the portion of the piezoresistive layer positioned at the intersection. A measurement system measures the resistance of each pressure sensor of the pressure sensor array. The measurement system includes a reading module with first op-amps connected to each row and second op-amps connected to each column. Plural switches switch between pressure sensor-enabled and pressure sensor-disabled positions to minimize a bus line crosstalk effect during pressure sensor reading A processor scans each pressure sensor and generates a pressure distribution profile based on a measured resistance of each pressure sensor.

Abstract: The present invention provides a thin, bendable, printed, layered primary battery structure without a battery separator. The battery includes a first layer including a printed positive electrode. A second layer includes a negative electrode material which may be a printed negative electrode or a metal foil negative electrode. An adhesive, UV-curable intermediate layer is adhered to the first layer on a first side of the intermediate layer and is adhered to the second layer on a second side of the intermediate layer. The intermediate layer includes a water-soluble electroactive material and a water-soluble viscosity-regulating polymer in an amount sufficient to render the intermediate layer adhesive. The intermediate layer also includes a water-insoluble polymer matrix having sufficient rigidity to prevent contact of the first layer and the second layer. A flexible package encases the first, second, and intermediate layers.

Abstract: A self-densifying interconnection is formed between a high-temperature semiconductor device selected from a GaN or SiC-based device and a substrate. The interconnection includes a matrix of micron-sized silver particles in an amount from approximately 10 to 60 weight percent; the micron-sized silver particles having a particle size ranging from approximately 0.1 microns to 15 microns. Bonding particles are used to chemically bind the matrix of micron-sized silver particles. The bonding particles are core silver nanoparticles with in-situ formed surface silver nanoparticles chemically bound to the surface of the core silver nanoparticles and, at the same time, chemically bound to the matrix of micron-sized silver particles. The bonding particles have a core particle size ranging from approximately 10 to approximately 100 nanometers while the in-situ formed surface silver nanoparticles have a particle size of approximately 3-9 nanometers.
