Embodiments of the disclosed invention provide wearable devices that use a humidity sensor to measure sweat rate generated from an area of skin. A sensing chamber is continuously filled with a sweat sample, which forms a droplet and alters the humidity measured within the chamber. Once the sweat sample droplet expands to the edge of the chamber, the droplet contacts a wick and is drawn away, so the chamber can fill with a subsequent droplet. The device uses a droplet volume and the time required to reach a maximum humidity to calculate a sweat rate. A pump is used to draw old sweat sample out of the wick to allow extended device operation. Some embodiments also include capacitive sensors to perform back up measurements. Another set of embodiments includes alternatively shaped sensing chambers configured to reduce sample volumes or improve function. A method for determining sweat rate based on humidity sensor measurements is also included.

The disclosure is and includes at least an apparatus, system and method for correlating bodily fluids to health aspects. The apparatus, system and method includes a slug comprising a passive chemical sensor, a receiving channel for wicking the bodily fluids from a body to the passive chemical sensor, and an interface for interfacing the passive chemical sensor to a mobile device; at least one indicator associated with the passive chemical sensor, wherein the at least one indicator changes based on features of the wickable bodily fluids; and at least one computing memory device associated with the mobile device comprising at least comparative lookup table of an application, wherein the at least one indicator is compared to the comparative lookup table to produce a user display on the application of the health aspects indicated by the at least one indicator.

Systems, devices and methods are described herein for various embodiments of a sample analysis system that is worn by a user, the sample analysis system configured to collect a sample of bodily fluid, and measure and analyze the bodily fluid to determine a property of the bodily fluid and/or a health parameter (e.g., degree of hydration, electrolyte losses, perspiration rate, etc.) of the user.

To objectively grasp a stress state of a user and to prevent a mental disorder of the user, the following steps are performed: acquiring, via a network, biogas information at multiple timings and time information corresponding to each of the multiple timings, wherein the biogas information represents a concentration of benzyl alcohol of a user acquired by a sensor that detects benzyl alcohol discharged from a skin surface of the user; obtaining reference information representing an upper limit of a normal range of the concentration of benzyl alcohol per unit period of time, using a memory storing the reference information representing the upper limit of the normal range; determining a stress time period during which a concentration of the benzyl alcohol of the user is more than the upper limit of the normal range, based on the acquired biological gas information; and outputting time period information indicating the determined stress time period to an information terminal of the user, to display the stress time period indicated by the time period information on a display of the information terminal.

A system provides ultra-wideband (UWB) positioning. The system exchanges ranging signals at a first rate between a UWB beacon and a UWB tag. The system then determines movement or location information of the UWB tag; and select, based on the movement or location information, a second rate for exchanging subsequent ranging signals between the UWB beacon and the UWB tag. The system then exchanges the subsequent ranging signals at the second rate between the UWB beacon and the UWB tag.

Skin-mounted or epidermal devices and methods for monitoring biofluids are disclosed. The devices comprise a functional substrate that is mechanically and/or thermally matched to skin to provide durable adhesion for long-term wear. The functional substrates allow for the microfluidic transport of biofluids from the skin to one or more sensors that measure and/or detect biological parameters, such as rate of biofluid production, biofluid volume, and biomarker concentration. Sensors within the devices may be mechanical, electrical or chemical, with colorimetric indicators being observable by the naked eye or with a portable electronic device (e.g., a smartphone). By monitoring changes in an individual's health state over time, the disclosed devices may provide early indications of abnormal conditions.

A technology for a wearable medical device for monitoring medical parameters. Medical measurement data can be received at the wearable medical device from a medical measurement sensor attached to the wearable medical device or a medical measurement sensor in communication with the wearable medical device. A calibration coefficient can be determined for calibrating the wearable medical device based on the medical measurement data. The wearable medical device can be calibrated based on the calibration coefficient.

Systems and methods for wireless sensing include a wireless senor which includes a physiological sensor and an identification sensor. The physiological sensor obtains physiological data from a patient and the identification sensor detects a unique characteristic of the patient as identification data. The identification data is used to produce a unique identifier which is transmitted wirelessly from the wireless sensor along with the physiological data to associate the transmitted physiological data to the patient.

A method includes: acquiring, via a network, biogas information at multiple timings and time information corresponding to time at each of the multiple timings, wherein the biogas represents a concentration of 2-ethylhexanoic acid of a user acquired by a sensor that detects the 2-ethylhexanoic acid discharged from a skin surface of the user; obtaining reference information representing a lower limit of a normal range of 2-ethylhexanoic acid per unit period of time, using a memory storing the reference information representing the lower limit of the normal range; determining a stress time period during which a concentration of the 2-ethylhexanoic acid of the user is less than the lower limit of the normal range, based on the acquired biogas information; and outputting time period information indicating the determined stress time period to an information terminal of the user.

A system having a scope with a longitudinal length extending between a proximal end and a distal end includes a plurality of markers spaced along the longitudinal length. The system also includes a disassociation and positioning device that is configured to enhance unsedated transnasal endoscopic procedures by at least partially occluding the vision of a patient while enabling body cavity access, and optionally record and sense body functions such as temperature, heart rate and oxygenation of the blood stream. The system further includes a sensor integrated into the distraction device, wherein the sensor is configured to detect the markers on the longitudinal length of the scope.
