Methods of forming garments having one or more stretchable conductive ink patterns. Described herein are method of making garments (including compression garments) having one or more highly stretchable conductive ink pattern formed of a composite of an insulative adhesive, a conductive ink, and an intermediate gradient zone between the adhesive and conductive ink. The conductive ink typically includes between about 40-60% conductive particles, between about 30-50% binder; between about 3-7% solvent; and between about 3-7% thickener. The stretchable conductive ink patterns may be stretched more than twice their length without breaking or rupturing.

A wearable electronic device (100) comprises a sensor (1) providing a sensor signal (s1), which sensor (1) is one of a temperature sensor and a humidity sensor. A control unit (3) determines, subject to at least the sensor signal (s1), if the wearable electronic device (100) is worn by a user, and provides an output signal (t1) indicative of a result of the determination.

Devices and methods are provided for continuous measurement of an analyte concentration. The device can include a sensor having a plurality of sensor elements, each having at least one characteristic that is different from other sensor(s) of the device. In some embodiments, the plurality of sensor elements are each tuned to measure a different range of analyte concentration, thereby providing the device with the capability of achieving a substantially consistent level of measurement accuracy across a physiologically relevant range. In other embodiments, the device includes a plurality of sensor elements each tuned to measure during different time periods after insertion or implantation, thereby providing the sensor with the capability to continuously and accurately measure analyte concentrations across a wide range of time periods. For example, a sensor system 180 is provided having a first working electrode 150 comprising a first sensor element 102 and a second working electrode 160 comprising a second sensor element 104, and a reference electrode 108 for providing a reference value for measuring the working electrode potential of the sensor elements 102, 104.

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.

Support structures for positioning sensors on a physiologic tunnel for measuring physical, chemical and biological parameters of the body and to produce an action according to the measured value of the parameters. The support structure includes a sensor fitted on the support structures using a special geometry for acquiring continuous and undisturbed data on the physiology of the body. Signals are transmitted to a remote station by wireless transmission such as by electromagnetic waves, radio waves, infrared, sound, and the like or by being reported locally by audio or visual transmission. The physical and chemical parameters include brain function, metabolic function, hydrodynamic function, hydration status, levels of chemical compounds in the blood, and the like. The support structure includes patches, clips, eyeglasses, head mounted gear and the like, containing passive or active sensors positioned at the end of the tunnel with sensing systems positioned on and accessing a physiologic tunnel.

Provided herein is a skin resistance measuring device having a simple structure and capable of accurately measuring a skin resistance. An AC voltage generated by a high-frequency power source (21) is applied to a first electrode (11). A detection circuit (30) detects a current of a second electrode (12). An inductive element (25) is provided, for example, in an electric path extending from the high-frequency power source (21) to the first electrode (11). A controller (40) changes and controls a frequency of the high-frequency power source (21), receives a detection signal (S1) from the detection circuit (30), and calculates an impedance of the human body which has touched an electrode section (10). The skin resistance of the human body is calculated based on a value of impedance at a frequency where the impedance is a minimum.

An auto-powered biosensor capable detecting a target molecule, and a method of powering the same, wherein the biosensor is fabricated with a microfluidics layer, a multimodal sensing layer comprising a biofuel cell and an electrode, and a logic circuit that may include a processor and non-transitory memory with computer executable instructions embedded thereon.

Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

A monitoring apparatus for monitoring a subject (14) is disclosed. The monitoring apparatus comprises a storage device (18) for storing first skin secretion data (27) of the subject. A detection unit (12) detects a skin secretion at a skin portion of the subject and provides second skin secretion data (28) of the subject. An evaluation unit (16) evaluates the second skin secretion data and determines at least one physical parameter on the basis of the first skin secretion data and the second skin secretion data. One of the at least one physical parameter is a time value (25, 26) determinable on the basis of a difference between the first and the second skin secretion data.
