International Classification:

G06F 19/00
G06N 99/00

Abstract:

A mobile medical device for monitoring a respiratory condition in a subject, the medical device including: a sensor configured to be adhered to the skin of a patient, the sensor configured to yield a resistance signal that is modulated by movements of a chest of a patient during respiration; a sensor attachment module configured to receive the signal from the sensor and to output data to a mobile electronic device an indication of an adverse respiratory event. Also disclosed is a server for integrating data collected from a plurality of the mobile medical devices and a crowd-sourced respiration advisory system including a plurality of the mobile medical devices and a server for integrating data collected by the mobile medical devices.

International Classification:

G01N 33/543
G01N 27/327

Abstract:

A sensor including a flexible substrate, a conductor disposed on the flexible substrate, and a hydrophilic surface coating disposed on the conductor. The flexible substrate and the conductor form wrinkle as a result of the substrate being shrunk. The hydrophilic surface coating is disposed in, e.g., fills, the wrinkles or covers surface areas of the conductor within invaginations of the wrinkles. Also disclosed are methods of preparing the sensor and methods of detecting an amount of an analyte in an aqueous solution. Methods of detecting an amount of analyte can include contacting the sensor with an aqueous solution, and detecting an electrical signal with the sensor, wherein the electrical signal is indicative of the amount of the analyte.

International Classification:

A61B 5/00
A61B 5/145
A61B 5/0205

Abstract:

An apparatus comprising a wearable device comprising a supporting structure, a sensor and an electronics module, wherein the supporting structure is configured to press the sensor against a skin surface of a subject, wherein the sensor is configured to detect a biological metric of the subject, and wherein the electronics module is configured to quantify and/or transmit one or more signal(s) corresponding to the biological metric. Some aspects relate to a method of monitoring a biological metric in a subject comprising: adorning a subject with the wearable device; and detecting the biological metric over a period of time in the subject with the wearable device. Other aspects relate to a method of treating a disease in a subject comprising: monitoring a biological metric in the subject over a period of time, and treating the subject with a therapeutic protocol, and monitoring the biological metric in the subject to assess treatment efficacy. Method are provided for estimating a central aortic pressure waveform in a subject comprising: measuring a radial artery pressure waveform in the subject and transforming the radial artery pressure waveform to a central aortic pressure waveform using a transfer function.

Abstract:

A wearable sensor apparatus is disclosed that includes a flexible substrate adapted to be coupled with a skin surface of an expectant mother. A conductor is disposed on the flexible substrate. The conductor can include micron-scale invaginations. The conductor can be capable of repeatable variation in resistance when subject to a strain. Also disclosed is a system for monitoring the health of a fetus in utero that includes a wearable sensor apparatus. The wearable sensor apparatus is configured to output a signal responsive to an electrical input. The system includes a computing system with one or more hardware processors. The computing system is programmed to implement a signal processing module configured to access the output signal from the wearable strain gauge and generate an output indicative of health of the baby in utero. The output can be based in part on the received output signal and previously stored correlations between signal data from the wearable strain gauge and observations of the system or of the mother. A user interface module can be provided and can be configured to display an output indicative of health of the baby in utero.
