  • Patent number: 11260943
    Abstract: Methods and devices including implantable micro-sensors used to detect tissue-dissolved inert gas and to detect microbubble formation to avoid Caisson disease are described. The disclosed methods and devices are based on measuring the refractive index changes in hydrophobic liquids after absorbing an inert gas such as nitrogen. The changes in the refractive index are based on implementing one of an interferometry, optical microcavity resonance shift, a photonic crystal resonance, a beam deflection, a resonance tuning or detuning, an amplitude change, or an intensity change method.

  • Publication number: 20210363581
    Abstract: FRET-based analytes detection and related methods and systems are described where a pair of FRET labeled primers and/or oligonucleotides are used that are specific for target sequences located at a distance up to four time the Förster distance of the FRET chromophores presented on the FRET labeled primers and/or oligonucleotides one with respect to the other in one or more polynucleotide analyte; in particular the pair of FRET labeled primers and/or oligonucleotides is combined with a sample and subjected to one or more polynucleotide amplification reactions before measuring FRET signals from at least one FRET chromophore.

  • Patent number: 11060511
    Abstract: Artificial muscles comprising a body of dielectric elastomer, wherein the body contains a pair of microfluidic networks are presented. Each microfluidic network includes a plurality of channels fluidically coupled via a manifold. The channels of the microfluidic networks are interdigitated and filled with conductive fluid such that each set of adjacent channels functions as the electrodes of an electroactive polymer (EAP) actuator. By using the manifolds as compliant wiring to energize the electrodes, artificial muscles in accordance with the present disclosure mitigate some or all of the reliability problems associated with prior-art artificial muscles.

  • Publication number: 20210098076
    Abstract: This disclosure provides methods, systems, compositions, and kits for the multiplexed detection of a plurality of analytes in a sample. In some examples, this disclosure provides methods, systems, compositions, and kits wherein multiple analytes may be detected in a single sample volume by acquiring a cumulative measurement or measurements of at least one quantifiable component of a signal. In some cases, additional components of a signal, or additional signals (or components thereof) are also quantified. Each signal or component of a signal may be used to construct a coding scheme which can then be used to determine the presence or absence of any analyte.
