  • Patent number: 11977025
    Abstract: Gas sensors are disclosed having an on-board, low-power data processor that uses multivariable gas classification and/or gas quantitation models to perform on-board data processing to resolve two or more gases in a fluid sample. To reduce computational complexity, the gas sensor utilizes low-power-consumption multivariable data analysis algorithms, inputs from available on-board sensors of ambient conditions, inputs representing contextual data, and/or excitation responses of a gas sensing material to select suitable gas classification and/or gas quantitation models. The data processor can then utilize these gas classification and quantitation models, in combination with measured dielectric responses of a gas sensing material of the gas sensor, to determine classifications and/or concentrations of two or more gases in a fluid sample, while consuming substantially less power than would be consumed if a global comprehensive model were used instead.

  • Patent number: 11911582
    Abstract: Disclosed herein is an instrument that enables the in situ formation of architected planar biomaterials and tissues by translating a printer head along a deposition surface such as a patient having burn injuries. In handheld embodiments of the instrument, cell-laden biopolymer solutions are perfused through a moving microfabricated printer head and deposited onto a stationary planar surface or a wound. The printer head may be translated via a drive mechanism. A soft deformable roller mitigates further damage to the injured area of skin as it rolls over it and a gimbal mechanism to which the printer head is attached is in contact with the injured tissue but is configured so that the printer head while in contact with tissue, does not exert undue pressure on the would area.

  • Publication number: 20210354360
    Abstract: Systems, devices and methods are provided for fabricating anisotropic polymer materials. According to various embodiments, a fluidic device is employed to distribute a polymer solution and a flow-confining solution in order to generate a layered flow, where the layered flow is formed such that a polymer liquid sheet is sheathed on opposing sides by flow-confining liquid sheets. The fluidic device includes first and second fluid conduits, where the first fluid conduit receives the layered flow. The second fluid conduit has a reduced height relative to the first fluid conduit, such that the layered flow is constricted as it flows through the second fluid conduit. The constriction formed by the second flow conduit causes hydrodynamic focusing, reducing the thickness of the polymer liquid sheet, and inducing molecular alignment and anisotropy within the polymer liquid sheet as it is hardened and as strain is applied during extrusion of the sheet.
