Abstract
This article deals with the creation of a power supply system of wireless sensors which take measurements and transmit data at time intervals, the duration of which is considerably less than the activation period of sensors. The specific feature of the power supply system is the combined use of devices based on various physical phenomena. Electrical energy is generated by thermoelectrochemical cells. The temperature gradient on the sides of these cells is created by a vortex tube. A special boost DC/DC converter provides an increase in the output voltage of thermoelectrochemical cells up to the voltage that is necessary to power electronic devices. A supercapacitor is used to store energy in the time intervals between sensor activation. A study of an experimental sample of the power supply system for wireless sensors was conducted. Using the model in MATLAB + Simulink program, the possibility and conditions for creating the considered system for a particular type of wireless sensor were shown.

The rapid depletion of mineral resources has spurred the development of alternative energy sources
This paper proposes and analyzes the wireless sensor node (WSN) power supply system, which can be applied to gas transportation by pipelines
There are three independent systems—a gas pipeline through which gas flows under pressure up to 10 MPa (100 bar); a vortex tube of Ranque–Hilsch, which is able to separate the gas flow with the creation of a temperature gradient (Equation (1)); and a thermoelectric converter, which is able to convert the energy of the temperature gradient into electrical energy (Equations (4)–(6))
Summary
The rapid depletion of mineral resources has spurred the development of alternative energy sources. Wind turbines, and geothermal power plants are gradually replacing traditional energy sources [1]. Alternative energy sources are quite scalable, which makes them indispensable in areas where it is not advisable to build a power transmission line, and, to build a fully fledged power plant [2]. A trend in the construction of WSN power supply systems based on the collection and accumulation of environmental energy has been intensively developed. Thermoelectrochemical cells, capable of converting the temperature gradient into electrical energy, are a promising and widely studied system [13]. With their ability to harvest low-temperature-gradient energy, the main disadvantage is the need for heat removal from the cold side. Using the converted energy of the gas stream into electrical energy is one way to increase the stability of the energy system
