The present disclosure is related to a method of producing a microfluidic sorting apparatus. The method includes providing an injection-molded substrate comprising a network of channels; bonding an insulating film to an upper surface of the substrate to cover the network of channels; and depositing a conductive film on the insulating film. The substrate can be separated from the conductive film.

Systems and methods for multi-junction particle sorting in injection-molded articles

A device for estimating a mechanical property of a sample is disclosed herein. The device may include a chamber configured to hold the sample; a transmitter configured to transmit a plurality of waveforms, including at least one forcing waveform; and a transducer assembly operatively connected to the transmitter and configured to transform the transmit waveforms into ultrasound waveforms. The transducer assembly can also transmit and receive ultrasound waveforms into and out of the chamber, as well as transform at least two received ultrasound waveforms into received electrical waveforms. The device also includes a data processor that can receive the received electrical waveforms; estimate a difference in the received electrical waveforms that results at least partially from movement of the sample; and estimate a mechanical property of the sample by comparing at least one feature of the estimated difference to at least one predicted feature, wherein the at least one predicted feature is based on a model of an effect of the chamber wall. Finally, the device can also include a controller configured to control the timing of the ultrasound transmitter and data processor.

Determining mechanical properties via ultrasound-induced resonance

Disclosed herein are liquid conductive wires and methods for making and using the same. Liquid conductive wires can be used in flexible, reconfigurable, dynamic and transparent electronic devices. Liquid conductive wires can be used in a variety of systems including, but not limited to, soft robotics.

Using ionic liquids to make reconfigurable liquid wires

A disposable system, in some embodiments, includes a multi-channel or multi-chamber test cartridge device configured to operate with a testing system for evaluation of hemostasis in a subject by in vitro evaluation of a test sample from the subject. The disposable system, in some embodiments, is configured to interrogate the test sample to evaluate clot stiffness, strength, or other mechanical properties of the test sample to assess the function of various physiological processes occur during coagulation and/or dissolution of the resulting clot.

Disposable system for analysis of hemostatic function

Systems are provided for detecting the flow of blood in vasculature by illuminating the blood with a source of coherent illumination and detecting one or more time-varying properties of a light speckle pattern that results from the scattering of the coherent illumination by tissue and blood. The movement of blood cells and other light-scattering elements in the blood causes transient, short-duration changes in the speckle pattern. High-frequency sampling or other high-bandwidth processing of a detected intensity at one or more points in the speckle pattern could be used to determine the flow of blood in the vasculature. Such flow-measuring systems are also presented as wearable devices that can be operated to detect the flow in vasculature of a wearer. Systems and methods provided herein can additionally be applied to measure flow in other scattering fluid media, for example in a scattering industrial, medical, pharmaceutical, or environmental fluid.

Non-invasive flow monitoring

Disclosed herein are systems and methods capable of identifying, tracking, and sorting particles flowing in a channel, for example, a microfluidic channel having a fluid medium. The channel and the fluid medium can have a similar refractive index such that they appear translucent or transparent when illuminated by electromagnetic radiation. The particles can have a refractive index substantially different from that of the channel and the medium, such that the particles interfere with the electromagnetic radiation. A sensor can be disposed adjacent to the channel to record the electromagnetic radiation. The sensor can be used for identifying, tracking, and sorting the particles.

Systems and methods for maintaining constant volumetric flow rates in a fluid channel

A system for collecting data for assessment of cardiovascular function includes a plurality of monitoring devices coupled to different respective body parts. Each monitoring device is configured to measure a respective signal at the respective body part in response to cardiovascular activity. The respective signal includes a cardiovascular component attributable to the cardiovascular activity and an artifact component not attributable to the cardiovascular activity. When the monitoring devices measure the respective signals simultaneously over a same time period, the cardiovascular components are correlated, and the artifact components are not correlated. The system also includes a controller configured to: identify the cardiovascular components included in the signal measurements, according to the correlation of the cardiovascular components; reject the artifact components included in the signal measurements, according to the non-correlation of the artifact components; and determine cardiovascular information from the identified cardiovascular components for an assessment of cardiovascular function.

Cardiovascular monitoring using combined measurements

Systems and methods are provided for detecting the flow of blood or other fluids in biological tissue by illuminating the biological tissue with two or more beams of coherent light and detecting responsively emitted light. A difference in wavelength, coherence length, beam divergence, or some other property of the beams of illumination causes the beams to preferentially scatter from, be absorbed by, or otherwise interact with respective elements of the biological tissue. Flow properties in one or more regions of the biological tissue (e.g., a region with which both beams of light preferentially interact, a region with which only one of the beams preferentially interacts) could be determined based on detected responsively emitted light from the biological tissue. Variations in speckle patterns over time and/or space, Doppler shifts, or some other properties of the detected light could be used to determine the flow properties.

Applications of hyperspectral laser speckle imaging

Disclosed herein are systems and methods capable of identifying, tracking, and sorting particles or droplets flowing in a channel, for example, a microfluidic channel having a fluid medium. The channel and the fluid medium can have a similar refractive index such that they appear translucent or transparent when illuminated by electromagnetic radiation. The particles or droplets can have a refractive index substantially different from that of the channel and the medium, such that the particles or droplets interfere with the electromagnetic radiation. A sensor can be disposed adjacent to the channel to record the electromagnetic radiation. The sensor can be attached to a system for identifying, tracking, and sorting the droplets.

Systems and methods for detecting particles in a fluid channel

Disclosed methods and systems may be operable to obtain non-contact diagnostic information about movements of scattering objects such as fluids in subsurface vasculature in tissue. As an example, a method may include causing a light source to illuminate the tissue with at least a first portion of the emitted light and illuminate an optical modulator with at least a second portion of the emitted light. The second portion of the emitted light may be modulated by the optical modulator. An offset source is configured to provide an offset frequency signal. An image sensor may receive optical information from the sample. A heterodyne signal based on the reference frequency signal and the offset frequency signal may be used as a gain input of each detector element of the image sensor. Based on the received information, a movement of a portion of the sample may be determined.
