摘要： Thin-film pressure sensors are disclosed herein. Such sensors include one or more electrodes in contact with a sensing material. As the sensor deforms the capacitance of the sensor varies and is measurable either between two electrodes of the sensor, or between the one electrode of the sensor and an electrode formed by the surface to which the sensor is applied, such as skin. The sensing material can be an ionic material such as an ionic composite including an ionic liquid.

摘要： A fabric-based pressure sensor assembly utilizing in ionic material and conductive material is disclosed. The sensing device can be applied in several various wearable health and biomedical applications on complex body topologies. As an alternative to conventional flexible sensors, the fabric-based sensor assembly yields high device sensitivity and desirable parameters for pressure sensing in a wearable construct. The sensor assembly enables rapid mechanical responses (in the milliseconds range) for high-frequency biomechanical signals, e.g., blood pressure pulses and body movements. The fabrication process for the device is low-cost highly compatible with existing industrial manufacturing processes.

摘要： An all-fabric iontronic supercapacitive pressure sensing device utilizing a novel iontronic nanofabric as the sensing element is disclosed. The sensing device can be applied in several various wearable health and biomedical applications on complex body topologies. As an alternative to conventional flexible sensors, the all-fabric iontronic pressure sensor provides an ultrahigh device sensitivity with a single Pascale resolution. The device also allows rapid mechanical responses (in the milliseconds range) for high-frequency biomechanical signals, e.g., blood pressure pulses and body movements. The fabrication process for the device is low-cost highly compatible with existing industrial manufacturing processes.

摘要： A fabric based digital droplet flowmetry (DDF) method and platform are provided utilizing a fluid collection network, a microfluidic junction for droplet formation and removal, and digital counting and measurement circuitry. The fluidic junction has a droplet emitter, such as a nozzle, and droplet receiver separated by a gap. The measurement circuitry detects the transient formation of a liquid bridge (the closed-circuit state) and the breakup of the bridge (the open-circuit state) as an electrical switching event. The duration of the bridge formation only lasts for a few milliseconds. The platform produces consistent droplet volume over varying flow rates and droplet size is controlled by the selection of structural parameters such as nozzle dimensions, channel geometries, surface wettability, and inlet/outlet pressures.

摘要： A telemedical interface pressure monitoring system is provided for intermittent or continuous monitoring of the pressure that occurs at the interface between the body and a support surface such as with a compression device, cast or resting surface. The system simultaneously measures interface pressure at multiple compression positions as well as provide real-time measurement data to both patients and clinicians. The system uses an array of one or more sensors and a data collection and transmission node with a microprocessor and transmitter/receiver that transmits the sensor data to a receiver such as a mobile device or cloud or clinic server for remote display, evaluation and automatic recording. Remote receivers can also control compression devices associated with the node.
