Abstract: This disclosure generally relates to compositions with omniphobic properties, and methods of preparing the compositions thereof. The omniphobic compositions can be used as coatings to make omniphobic materials, which can be used to manufacture a variety of apparatuses such as wearable devices, e.g., hearing aids.

Abstract: Cosmetic and dermatological compositions, including color changing compositions, are provided which typically include a plurality of synthetic particles having a size in the micrometer or nanometer range. Each synthetic particle typically includes one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45; the aggregates having a size larger than about 100 nm and the composition being biodegradable and biocompatible.

Abstract: Processes, scales, and devices to measure and quantify wetness perception in humans. Exemplary devices and scales utilize sensor fusion of temperature and pressure modalities, for which humans have dedicated receptors in the skin, to understand how the perception of wetness comes about. Processes test the utility of wetness perception as a biomarker for assaying peripheral neuropathy. Wetness perception devices include a Peltier module. The temperature of the Peltier module can be varied precisely using a computer-aided feedback system, mounted on a load scale to enable concomitant pressure measurements. Devices may include an insulation chamber with desiccators in place to lower internal humidity and prevent condensation. Wetness perception can be used as a non-invasive biomarker for disease-related peripheral neuropathy in which sensory mechanisms are disrupted.

Abstract: Biologically-inspired compositions, including color changing compositions, and corresponding embodiments such as sensors, textile materials, coatings and films, are provided which typically include a solid, transparent and nondegradable matrix. The matrix contains a plurality of (i) synthetic particles having a size in the micrometer or nanometer range, each synthetic particle including one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45, the aggregates having a size larger than about 100 nm; or (ii) submicrometer natural particles extracted and purified from homogenized tissue.

Abstract: A sensor array embedded within a flexible layer. The sensors, which can be transducers, are controlled by local electronics also embedded within the flexible layer. The invention includes numerous different arrangements of these electronic controllers and their associated transducers. For example, each transducer can have its own controller embedded nearby. Alternatively, one controller can control a number of transducers, and can therefore be embedded in various configurations proximate to one or more of the transducers it controls. The controllers can include various components that impart other advantages, such as wireless transceivers for reducing the number of wires needed within the flexible layer, and local processors for reducing or eliminating the need for a remote data processor.
