Abstract: The disclosure relates to multifunctional sensors for mobile applications, namely to a miniature optical sensor for remote micro- and macro-object detection and characterization. The disclosure makes it possible to reduce the size of the sensor, this provides for surface mount of the sensor in any microcircuit of a mobile device. The sensor is multifunctional, low-power, vibration-resistant. The sensor comprises at least one pair consisting of a radiation source and a corresponding radiation receiver, an optical circuit including a collimating element, a first optical element, a second optical element. The first optical element and the second optical element are interconnected by a common surface, the common surface being a semitransparent surface. The sensor may be used simultaneously as a microphone, a dust sensor, a lidar, and a photoplethysmogram (PPG) sensor.

Abstract: A device and a method for metabolism monitoring of a user based on low-cost, energy-effective and ultra-compact metal-oxide semiconductor (MOS) sensor are provided. The device provides information on metabolism/nutrition/physical activity of the user based on measuring the MOS sensor resistance proportional to a ratio of oxygen (O2) to carbon dioxide (CO2) concentrations in exhaled air.
