摘要： A method, system, apparatus, and/or device to determine a condition of a user using a wearable device with a miniaturized spectrometer. The method, system, apparatus, and/or device may include: a band configured to extend at least partially around a body part of a user, the body part comprising an internal feature within the body part; a light source embedded in the band, where the light source is configured to emit light into the body part as the user wears the band; a collimator; an optical filter; and an optical sensor, where the collimator, optical sensor, or the optical filter are arranged together to form a stack embedded in the band.

摘要： A method, system, apparatus, and/or device to determine a condition of a user based on a heartbeat waveform. The method, system, apparatus, and/or device may include: a miniaturized impedance sensor configured to take a measurement from a muscular-walled tube within a body part of a user, where the miniaturized impedance sensor includes a first set of miniaturized electrodes configured to generate a signal within the muscular-walled tube and a second set of miniaturized electrodes configured to measure the signal; and a processing device programmed to interrogate the muscular-walled tube via the miniaturized impedance sensor. The processing device may be configured to generate the signal by the first set of miniaturized electrodes; measure the signal by the second set of miniaturized electrodes; generate a heartbeat waveform; and determine a condition of the user based on the heartbeat waveform.

摘要： A method, system, apparatus, and/or device to determine a condition of a user using a miniaturized collimator. The method, system, apparatus, and/or device may include: a carbon nanotube structure comprising a microtube that includes a set of aligned carbon nanotubes infiltrated by carbon and a through-channel, the carbon nanotube structure having a defined height to through-channel width aspect ratio, where: the defined height to through-channel width aspect ratio is based on a defined collimation to diffraction ratio; the set of aligned carbon nanotubes infiltrated by carbon is configured to absorb a first portion of light that travels through the through-channel at a first angle and impinges a side of a first through-channel portion; and the set of aligned carbon nanotubes infiltrated by the carbon is configured to allow a second portion of the light that enters the through-channel at a second angle to pass through the through-channel.

摘要： A method, system, apparatus, and/or device to determine a condition of a user using multiple sensors. The method, system, apparatus, and/or device may include: a band configured to extend at least partially around a body part of a user having a subdermal feature within body part; a light configured in the band to emit light into the body part; a miniaturized spectrometer positioned in the band to press against the body part to receive the light, where the miniaturized spectrometer comprises: an optical filter configured to isolate a relevant constituent wavelength of the light; a collimator configured to collimate the light; and an optical sensor configured to detect an intensity of the relevant constituent wavelength; and an impedance sensor integrated into the band and configured to be positioned against a same side of the body part as the miniaturized spectrometer.

摘要： A method, system, apparatus, and/or device to creating a set of miniaturized electrode pillars. The method, system, apparatus, and/or device may include patterning a set of miniaturized electrode pillars on a substrate and coating the set of miniaturized electrode pillars with an interstitial filler disposed between the set of miniaturized electrode pillars. The interstitial filler may insulate the set of miniaturized electrode pillars from each other and bolster the set of miniaturized electrode pillars.
