    摘要: Electronic textiles and methods of fabrication electronic textiles. Nanoparticles of a conductive material are sprayed along a conductive path into a fabric material so as to penetrate into the fabric. A layer of a second conductor material is coated over the nanoparticles along the conductive path. A layer of an insulator material is coated over the layer of the second conductor material so as to encapsulate the conductive path and form a trace. An electrode configured to contact a subject wearing the fabric material includes a layer of a third conductor material coated over the layer of the second conductor and electrically coupled with the conductive path. An electrical connector is secured to the fabric material and electrically coupled with the conductive path. The nanoparticles are sprayed onto the fabric material using a dual regime spray process implemented with a dual regime spray system.

    摘要: The present invention discloses a method of manufacturing a diaper that has multiple moisture sensing elements on interior side of its bottom impermeable layer or on any surface of the top permeable layer. The moisture sending elements are made by spraying conductive ink on a moving sheet of either the bottom impermeable layer or the top permeable layer, before other layers of the diaper are attached. Spraying of conductive ink on the moving sheet causes parallel lines of conductive inks to be formed on the layer. The parallel lines of conductive ink run through the entire length of either of the layers and are designed to get connected with a detecting device. When a user urinates inside the diaper, the moisture causes a closed circuit between at least two of the parallel lines of conductive inks. These formations of closed circuits, between parallel lines of conductive inks, are detected by the detecting device. Also, with increasing volume of moisture, the resistance of the closed circuits also tends to decrease. This rate of decrease of resistance is also detected by the detecting device and is used to calculate a volume of moisture present in the diaper. The detecting device then generates a suitable alarm to give an idea about the saturation level of the diaper. The process of manufacturing sensing elements by spraying conductive inks on moving sheet of layer reduces the processing and modification overhead of specially designed conductive ink printers and also does not impact the manufacturing time of a diaper manufacturing assembly line.

    摘要: Semiconductor layers useable for minimizing or preventing the growth of metal whiskers, as well as devices and methods utilizing the same and kits for making the same, are described. The semiconductor layers may be nickel oxide layers. In some embodiments, an electronic device may include a substrate, a first metal layer on the substrate, a semiconductor layer comprising NiO on the first metal layer, and a second metal layer on the semiconductor layer. In some embodiments, an electronic device may include a substrate, a semiconductor layer comprising NiO directly on the substrate, and a metal layer directly on the semiconductor layer. A method for making an electronic device may include depositing a semiconductor layer comprising NiO on a substrate, and depositing a metal layer on the semiconductor layer, where the semiconductor layer substantially prevents the growth of whiskers on the metal layer.
