  • Publication number: 20220379309
    Abstract: An electronically-controlled digital ferrofluidic device is disclosed which employs a network of individually addressable coils in conjunction with one or more movable permanent magnets, where each moveable permanent magnet delivers the designated fluid manipulation-based tasks. The underlying mechanism facilitating fluidic operations is realized by addressable electromagnetic actuation of miniaturized mobile magnets that exert localized magnetic body forces on droplets filled with magnetic nanoparticles. The reconfigurable, contactless, and non-interfering magnetic-field operation properties of the underlying actuation mechanism allow for the integration of passive and active components to implement advanced and diverse operations with high efficiency (e.g., droplet sorting, dispensing, generation, merging, mixing, filtering, and analysis).

  • Publication number: 20220061705
    Abstract: Active biofluid management may be advantageous to the realization of wearable bioanalytical platforms that can autonomously provide frequent, real-time, and accurate measures of biomarkers in epidermally-retrievable biofluids (e.g., sweat). Accordingly, exemplary implementations include a programmable epidermal microfluidic valving system capable of biofluid sampling, routing, and compartmentalization for biomarker analysis. An exemplary system includes a network of individually-addressable microheater-controlled thermo-responsive hydrogel valves, augmented with a pressure regulation mechanism to accommodate pressure built-up, when interfacing sweat glands. The active biofluid control achieved by this system may be harnessed to create unprecedented wearable bioanalytical capabilities at both the sensor level (decoupling the confounding influence of flow rate variability on sensor response) and the system level (facilitating context-based sensor selection/protection).
