The use of microneedles for discrete and continuous monitoring and correction of the body state is a progressive direction in personalized medicine. The desire to minimize the consequences of invasive diagnostic methods and increase the effectiveness of drug therapeutic effects determines the intellectualization of microneedles, their designs and technologies of use. Microneedles and their arrays are presented as complex functional microsystems, the creation of which is based on the use of micro- and nanote-chnology processes, as well as heterogeneous organic-inorganic compositions.

The constructive and technological solutions of a new-generation interactive multimodal hybrid conformal sensor-correcting microsystem are presented. Functional modules of the microsystem made in the form of an ultrathin bracelet or patch with the possibility of being fixed to human skin are considered. The advantages of the proposed microsystem, its purpose and possible applications are discussed.

The paper proposes physical-technological solutions that provide passive protection of miniature wearable objects of the bio-and technosphere from the effects of electromagnetic radiation in the frequency range from 50 MHz to 18 GHz. Various conformal micro- and nanocompositions of electromagnetic shields and electromagnetic wave absorbers have been proposed and studied.

PANI and PEDOT:PSS films were produced on a dielectric substrate and characterized by optical and electron microscopy. The absorption coefficient of electromagnetic radiation in films is measured using a coplanar transmission line. The possibility of using conductive polymers (PANI and PEDOT:PSS) as the basis for conformal radiation-absorbent materials designed to protect bio- and technosphere objects is shown.

AbstractThe samples of water-based magnetic fluid, which contain Fe_3O_4–SiO_2 particles with a spherical shape and sizes less than 100 nm, have been obtained. The method based on using a transmission line has been applied to measure the electromagnetic absorption coefficient in the frequency range from 0.1 to 18.0 GHz using a measuring setup based on horn antennas and the cell based on a coplanar transmission line. It has been found that magnetic fluids can be used to produce electromagnetic shields and electromagnetic wave absorbers as well as means to carry out local hyperthermia at electromagnetic radiation frequencies higher than 7 GHz.
