Disclosed are devices and methods for non-invasively measuring arterial stiffness using pulse wave analysis of photoplethysmogram data. In some implementations, wearable biometric monitoring devices provided herein for measuring arterial stiffness have the ability to automatically and intelligently obtain PPG data under suitable conditions while the user is engaged in activities or exercises. In some implementations, wearable biometric monitoring devices are provided herein with the ability to remove PPG data variance caused by factors unrelated to arterial stiffness. In some implementations, wearable biometric monitoring devices have the ability to perform PWA while accounting for the user's activities, conditions, or status.

An interstitial fluid sampling device with mechanical, electrical, and/or chemical components to mitigate sample quality issues and/or measure the quality of collected samples to alert of and/or correct for quality issues. The device includes at least one sensor that is specific to an analyte in the interstitial fluid, at least one wicking component, and at least one component to ensure the quality of collected interstitial fluid.

An article of manufacture for providing a wearable face and hand proximity detector is disclosed. The article includes a bracelet to be worn on a user's wrist and a necklace to be worn around the user's neck. One of these devices includes a signal transmitter that may be received by a receiver element in the other device. The received signal being detected provides an indication that the user's hand is nearing the user's face. When the signal is detected, an alarm is generated. The alarm may be an auditory signal or a physical vibration that may be felt by the user.

An analyte measurement device including an electronics housing including a shell having an upper surface with a first aperture defined therein; a mount mated to the shell and having an underside with a second aperture defined therein aligned with the first aperture; a collar disposed between the shell and the mount and including: a third aperture aligned with the first aperture and the second aperture, and a plurality of tabs on an outer periphery of the collar; a circuit board disposed within the electronics housing and including a plurality of electronic modules, wherein the circuit board is mounted within the electronics housing on the plurality of tabs on the outer periphery; and an analyte sensor including a tail portion extending through the first aperture and the second aperture and configured to measure an analyte level and a flag portion including a plurality of electrical contacts coupled with the circuit board, and a neck portion interconnecting the tail portion and the flag portion. An assembly for delivery of an analyte sensor is also disclosed.

The present invention discloses a holder carrying thereon a sensor to measure a physiological signal of an analyte in a biological fluid, wherein the sensor has a signal detection end and a signal output end, and the holder includes an implantation hole being a channel for implanting therethrough the sensor and containing a part of the sensor, and a containing indentation containing the signal output end, wherein the containing indentation has a surrounding wall kept apart from the signal output end to define a space.

A finger insert for use with a nailfold imaging device includes a housing to receive the user's finger and an immersion substance (e.g., immersion oil), and a deformable pad that holds the user's finger in place during imaging, as well as prevent bubble formation in the substance. The housing includes a transparent wall to facilitate imaging of the finger. The transparent wall includes multiple angled portions that prevent or reduce contact between the nailfold and the wall, to ensure sufficient blood flow through the nailfold region for imaging.
