摘要： A biometric measurement device including a photodiode array having a number of photodiodes and at least one polarization filter covering at least one of the photodiodes. The biometric measurement device also includes a light-emitting diode array having a number of light-emitting diodes proximate to the photodiode array, a non-volatile memory device, and a processor in electronic communication with the non-volatile memory device. The photodiode array is configured to receive a reflected waveform from light emitted from the light-emitting diode array, and the processor is configured to determine at least one physiological parameter based on a pulsatile (AC) component and a static (DC) component of the reflected waveform. The light-emitting diodes may emit polarized light.

摘要： A camera system includes two or more sensor arrays and an optical path. The sensor arrays are on the same sensor chip. Each sensor array includes the same field of view (FOV) as each other sensor array. The optical path includes a main lens and a metalens that are shared by each sensor array, and a microlens associated with each sensor array. The metalens splits incident light into different spectrums of light and directs each respective spectrum to a corresponding sensor array. The different spectrums of light include at least two of visible light, near infrared light, shortwave infrared and longwave infrared, and at least one sensor array includes single-photon avalanche diodes. The image processor that provides image processing, object recognition and object tracking and/or image fusion functionality may be on the same sensor chip as the sensor arrays.

摘要： A smart contact lens includes a contact lens, a nanostructures layer, a first sensor, a connector, and a smart module. The nanostructures layer may be anti-bacterial. The smart contact lens may be worn on an eye or may be implanted within an eye. The nanostructures layer is fabricated by depositing a colloidal dispersion onto an electrostatically-coated substrate. The colloidal dispersion is then removed and nanoholes are etched. The electrostatic coating is removed and a biocompatible material is spin-coated onto the substrate. Upon removal, a quasi-randomly distributed nanostructures layer forms.

摘要： Optical spectrometers may be used to determine the spectral components of electromagnetic waves. Spectrometers may be large, bulky devices and may require waves to enter at a nearly direct angle of incidence in order to record a measurement. What is disclosed is an ultra-compact spectrometer with nanophotonic components as light dispersion technology. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering nanostructures that may be randomized to create a large input angle, and the Bragg filter may result in the light dispersion independent of the input angle. The spectrometer may be capable of handling about 200 nm bandwidth. The ultra-compact spectrometer may be able to read image data in the visible (400-600 nm) and to read spectral data in the near-infrared (700-900 nm) wavelength range. The surface area of the spectrometer may be about 1 mm2, allowing it to fit on mobile devices.
