Research activities are focused on the development of energy-efficient integrated circuits for measuring and processing biological signals and integrated circuits for wireless transmission in sensor nodes of wireless sensor networks on the human body (Body Area Notworks - BAN). When designing a wireless sensor node, the size of the sensor node and power consumption are of particular importance as a critical parameter. For this reason, it is of crucial importance to minimize the circuit area and power consumption, which imposes the need for the design of application-specific integrated circuits (ASIC) with the aim of meeting specific user requirements. Also, research related to the development of new energy-efficient modulation procedures and methods of multi-user access will be carried out. The possibilities of improving the properties of communication systems based on orthogonal frequency multiplex, communication systems with spread spectrum and systems based on spatial modulation is analyzed. Special emphasis is placed on their application in systems for measuring biological signals, where energy efficiency and reduced circuit complexity are the most important requirements.
