  "abstract": "Described herein are apparatuses (e.g., garments, including but not limited to shirts, pants, and the like) for detecting and monitoring physiological parameters, such as respiration, cardiac parameters, and the like. Also described herein are methods of forming garments having one or more stretchable conductive ink patterns and methods of making garments having one or more highly stretchable conductive ink pattern formed of a composite of an insulative adhesive, a conductive ink, and an intermediate gradient zone between the adhesive and conductive ink. The conductive ink typically includes between about 40-60% conductive particles, between about 30-50% binder; between about 3-7% solvent; and between about 3-7% thickener. The stretchable conductive ink patterns may be stretched more than twice their length without breaking or rupturing.",

  "description_excerpt": "Described herein are wearable apparatuses (e.g., “garments”) that can communicate with a user and others, receive both direct (user-selected) input and indirect (user monitoring) input, for example, detecting to signals from the user (e.g. from a wearable electronics based garment) and store or transmit this information. In particular, described herein are wearable monitoring and input systems that can monitor physiological parameters from the wearer. These garments may include stretchable and conductive ink. For example, described herein are structures having enhanced conductivity and stretchability in which the conductive ink forms a partially-mixed gradient with an insulative and adhesive base that can be applied directly or transferred onto a compression fabric, and used to form wearable electronics.\n\nIn the last twenty years, the development of mobile telecommunications devices have has dramatically expanded and modified the ways in which people communicate. Computers with ever-faster computer processors enabled faster communication with increased processing speed and improved analysis of vast quantities of data. In addition, sensor technology has also rapidly expanded how patients have been monitored, even by non-professionals. The development of various sensors enabled a variety of measurements to be taken and analyzed by a computer to generate useful information.",
