The present disclosure provides methods for evaluating tissue damage and the use of spatial variation in Sub-Epidermal Moisture (SEM) values to determine damaged tissue for clinical intervention. The present disclosure provides methods of identifying deep and early-stage pressure-induced injuries or ulcers (PI/PU). The present disclosure provides algorithm for computing SEM delta values which inform clinical decision-making for developing intact skin PI/PUs including suspected deep tissue injury (sDTI) and Stage I PI/PUs.

Systems, methods, apparatus, and non-transitory computer readable media for measuring and analyzing galvanic skin response. Responses to stimuli including electromagnetic waves and mechanical waves, as well as substances exposed to electromagnetic waves and mechanical waves, are recorded and analyzed. Electromagnetic waves and mechanical waves are constructed based on biological outputs in one embodiment.

Systems, methods, apparatus, and non-transitory computer readable media for measuring and analyzing galvanic skin response. A system for measuring galvanic skin response includes an electrical conductivity meter (ECM) electrically connected to a positive electrode and a negative electrode and a server platform in network communication with the ECM. The ECM includes at least one processor and at least one memory. The positive electrode is in contact with a point on a hand or a foot of a subject. A circuit is created between the ECM and the subject including the positive electrode and the negative electrode. The positive electrode includes a pressure sensor to indicate an amount of pressure applied by a tip of the positive electrode on the point. The server platform includes artificial intelligence (AI) algorithms to detect variations in the pressure applied by the positive electrode during a session and/or across multiple sessions.

There are disclosed methods and apparatus for measuring water content in tissue in-vivo, for example in sub-surface or sub-cutaneous tissue of a human or animal subject. The measurement may be made through diffusely scattering overlying tissue such as skin tissue, by: directing probe light to an entry region on a surface of the overlying tissue; collecting said probe light from a collection region on the surface of the overlying tissue, the collection region being spatially offset from the entry region, the collected probe light comprising probe light inelastically scattered into the Raman OH stretching bands by water present in the sub-surface tissue; detecting, in the collected probe light, one or more first spectral features of the probe light inelastically scattered into the Raman OH stretching bands; and measuring water content in the sub-surface tissue using the one or more first spectral features.

Systems and methods for administering one or more hydration compositions to an individual to improve vascular health are provided. A system comprises a hydration composition delivery element and a sensor operatively coupled to the hydration composition delivery element. The sensor is configured to determine one or more of the intake of fluids, the amount of fluid discharged, the activity level of the patient, or level of hydration of the patient based on the level of fluid in the hydration composition delivery element. The system further includes a monitoring system which, based on a signal received from the sensor, provides an indication of one or more of the need to intake fluid, the identity of a specific hydration composition of a plurality of hydration compositions to be consumed or an amount of a hydration composition to be consumed.

A system for monitoring a health status of a person remotely from a medical facility, includes a display device to be installed in the medical facility, a wireless sensor device attachable to a leg of the person to acquire measurement information on a state of the leg of the person, and a compute server in wireless communication with the sensor device to acquire the measurement information. The compute server is configured to determine a risk of an arterial disease and a venous disease of the leg based on the acquired measurement information, and output, to the display device, information on the determined risk of the arterial disease and the venous disease of the leg.

The present disclosure relates to cardiac health assessment system for use with a handheld electronic device for assessing cardiac health of a user and a method for assessing cardiac health of a user. The disclosure further relates to systems and methods for training a machine learning model to estimate intracardiac pressure data.

A system for monitoring a health status of a person, includes a mobile terminal configured to display the status and in wireless communication with a first sensor attached to one leg of the person to acquire first information relating to a state of the one leg, and a second sensor attached to a part of a body of the person other than said one leg to acquire second information relating to a state of the part, and a server in communication with the terminal to acquire the first and second information from the sensors. The server is configured to compare the first and second information and determine a blood vessel state of said one leg based on its difference, and transmit to the terminal information indicating the blood vessel state. The mobile terminal is configured to update the status based on the information.

Provided is a contactless internal measurement device including an electromagnetic wave irradiation unit that irradiates an electromagnetic wave to a measurement subject, and an electromagnetic wave receiver that detects the electromagnetic wave reflected by the measurement subject. The electromagnetic wave irradiation unit is disposed to reduce a polarization component of the electromagnetic wave detected by the electromagnetic wave receiver, the polarization component being the same as a polarization component of the electromagnetic wave irradiated by the electromagnetic wave irradiation unit.

A moisture-sensitive device is provided that includes a dissolvable conductive material. Exposure of the dissolvable conductive material to urine or some other fluid causes the dissolvable conductive material to dissolve, increasing an effective resistance of the dissolvable conductive material. This change in resistance can be detected to determine the presence of an aqueous fluid. In response to such detection, a transmitter can then provide a wireless transmission indicative of the presence of the fluid. This moisture-sensitive device can be provided in a diaper and transmissions produced by the device can be detected using a smart phone or other device and used to indicate to a user that the diaper has been soiled.
