BISENSOR TRACKER FOR RECORDING VOLATILE MOLECULES RELEASED BY THE SKIN Russian patent published in 2023 - IPC G01N33/497 

FIELD: measuring equipment.

SUBSTANCE: invention is related to express analysis of mixtures of gases emitted by the skin. The bi-sensor tracker for registration of volatile molecules emitted by the skin includes a plastic case fixed on a strap for attaching to the arm, inside which there are electrical circuits connected by a rotary mechanism with two independently operating sorbent sensors with the same characteristics, which are located in the case parallel to each other and to the skin. On the side in contact with the hand, under the sensors, there is a hole in the case for molecules coming from the skin, and on the opposite side in the case, there is a hole for their natural removal from the surface of the sensors and the tracker. Electrical circuits are configured to be able to connect to an external power source and a Bluetooth device to pair with a phone, tablet, to control the tracker and transfer information from sensors to the software. The control of the power supply and the working state of the sensors is carried out by actuation when the three light indicators located on the upper part of the device case are turned on, respectively.

EFFECT: development of a device that allows continuous measurement and recording of volatile compounds emitted by the skin, without sampling and preparation, while maintaining information about the result of their interaction with sensors.
