Abstract: A system configured to monitor and characterize motions of a user is disclosed herein. The system can include a wearable article including a tubular body comprising a resilient material, a flexible circuit including a fluid-phase conductor configured to generate a first signal, and an inertial measurement unit (“IMU”) coupled to the resilient material, wherein the IMU is configured to generate a second signal. The system can further include a processor communicably coupled to the flexible circuit and the IMU.

Abstract: Devices, systems, and methods for making and using highly sustainable circuit assemblies are disclosed herein. In various aspects, the highly sustainable circuit assembly includes a substrate layer; and a pattern of contact points supported by the substrate layer. The pattern of contact points can be configured to correspond to at least one terminal of an electrical component. The pattern of contact points can include a deformable conductive material. The deformable conductive material can be a non-hazardous, readily reclaimable, readily recyclable material.

Abstract: Devices, systems, and methods for making and using circuit assemblies having a pattern of deformable conductive material formed therein are disclosed herein. In various aspects, a circuit assembly can include a substrate layer; a first pattern of deformable conductive material formed on a surface of the substrate layer using a removable stencil; and a first stacked layer configured to cover at least a portion of the first pattern of deformable conductive material.

Abstract: A flexible hybrid electronic system and method includes a first structure and a second structure. The first structure includes a first flexible substrate, a first electronic component secured to the first flexible substrate, and a first flexible conductive trace formed in part from conductive gel. The second structure includes a second flexible substrate, a second electronic component secured to the second flexible substrate, and a second flexible conductive trace formed in part from conductive gel. The first structure is bonded to the second structure at an interconnect region, the first conductive trace is electrically coupled to the second conductive trace within the interconnect region, and the first electronic component is operatively coupled to the second electronic component.

Abstract: A composition for sequestering a pathogen, for example, viral particles of a target virus in the respiratory tract of a subject is provided. The composition comprises an effective amount of sequestering particles having a protein binding agent on the surface of the sequestering particles. The protein binding agent binds a pathogenic surface protein, for example, capsid protein on the surface of the viral particles. The sequestering particles and the target pathogen, for example, viral particles, form aggregates. Also provided is the use of the composition for sequestering a target pathogen, for example, viral particles of a target virus, in the respiratory tract of a subject.
