摘要： A method, system, apparatus, and/or device to align a miniaturized impedance sensor over the muscular-walled tube of a user. The method, system, apparatus, and/or device may include: a band comprising a shape, size, and flexibility designed for attaching the band to a body part of a user, where the body part includes a dermal layer and a muscular-walled tube; a miniaturized impedance sensor embedded in the band and positioned in the band to be pressed against a portion of the body part adjacent to the muscular-walled tube as the user wears the band, where the miniaturized impedance sensor may include two or more miniaturized electrode strips or an array of miniaturized electrode pillars; and an alignment device embedded in the band and configured in the band to align the miniaturized impedance sensor over the muscular-walled tube as the user wears 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 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.

摘要： A method, system, apparatus, and/or device with a miniaturized impedance sensor. The method, system, apparatus, and/or device may include a substrate with locally non-flexible regions interconnected by a flexible material and a miniaturized impedance sensor disposed on the substrate. The miniaturized impedance sensor may include: an array of electrical contacts; an array of miniaturized electrodes disposed on the array of electrical contacts; and an interstitial filler disposed within the array of miniaturized electrodes. The locally non-flexible regions may correspond to subsets of the array of miniaturized electrodes. The locally non-flexible regions may retain shape as the flexible material changes shape.
