A method of analysing a skin-print comprises: receiving a skin-print on a substrate; performing a quantity test to obtain a quantity score for the skin-print; performing a chemical analysis of the skin-print to detect for the presence of one or more chemical species and thereby provide a chemical test result; and storing or transmitting the chemical test result together with the quantity score.

Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

A monitoring device includes a plurality of physiological sign monitoring portions. Each physiological sign monitoring portion of the device is configured for deployment on a different, respective surface of a subject including a surface on the back of an ear of the subject, a surface over a mastoid region of the neck of the subject, and a surface over another region of the neck of the subject. Each physiological sign monitoring portion of the device includes a plurality of physiological sensors, where each sensor is configured to generate a respective electronic signal based on a respective monitored physiological parameter of the subject. At least one physiological sensor in each physiological sign monitoring portion of the device is configured to generate a respective electronic signal based on the same monitored physiological parameter of the subject.

A method of measuring an analyte in a bodily fluid sample and combining measurement data from multiple users may involve initiating a wireless connection between a handheld analyzer and a smart computing device on which an analyte analysis application has been downloaded and inserting a test strip into the handheld analyzer. The method may further involve collecting a sample of a bodily fluid on the test strip, measuring, with the handheld analyzer, a concentration of at least one analyte in the sample, wirelessly communicating the measured concentration from the handheld analyzer to the smart computing device, and displaying the measured concentration on the smart computing device. Finally, the method may involve transmitting the measured concentration to a database and organizing data including the measured concentration and at least one additional measured analyte concentration from at least one additional user on the database.

A base material is made of a flexible resin, and formed in the shape of a sheet provided with a hollow portion. The base material can be wrapped around, for example, a forearm, an upper arm, a wrist, or the like. A sweat absorption unit is made of a plurality of fibers, and is arranged at the hollow portion for taking up sweat that has been taken in by a suction port. The sweat absorption unit is made of, for example, paper made of cellulose. A sodium ion detection electrode, a potassium ion detection electrode, and a reference electrode are allowed to contact the sweat that has been suctioned from the suction port of the sweat absorption unit and taken up into the sweat absorption unit, to detect ions contained in the sweat.

A flexible circuit comprising two or more circuit layers separated by one or more insulating layers; a plurality of nodes located on each of the circuit layers; and a processor configured to estimate the distribution of liquid within the circuit from the capacitance measured at one or more of the nodes.

Disclosed is an electronic device comprising a processor and at least one sensor circuit comprising at least a biometric sensor and a fatigue sensor. The processor may be configured so as to detect biometric data of an external object by means of the biometric sensor, detect fatigue data of the external object by means of the fatigue sensor if the biometric data exceeds a designated second range, and output, by means of a designated external device, a fatigue notification indicating a fatigued state if the fatigue data exceeds a designated third range. Other various embodiments identified in the description are possible.

For attaining the object described above, an information processing apparatus according to an embodiment of the present technology includes an acquisition unit and a generation unit. The acquisition unit acquires information related to a notification to a user. The generation unit generates control information for changing an outer shape of a wearable device on a basis of the information.

Presented herein are systems, methods for collecting fluid from a surface (e.g., skin) and analyzing the fluid (e.g., to measure chemical, physical and/or biological properties of the fluid). For example, a system for fluid collection on a surface (e.g., skin) and fluid analysis includes at least one of the following modules: (i) a collection and delivery module to collect a fluid over a wet or partially wet surface and deliver it to (ii) a main sensing module to perform chemical, physical and/or biological analysis on the fluid. The system also includes (iii) a flow regulation module, for controlling fluid flow (e.g., transport) through the system and (iv) a waste module to collect and/or dispose of the fluid after analysis is complete.

A system for collecting and analyzing sweat includes a sweat sensing device having at least one sensor configured to sense one of physiologic information, biologic information, biochemical information, and biometric information, from skin of a person to whom the sweat sensing device is attached.
