Towards Electron-Beam-Driven Soft / Polymer Fiber Microrobotics for Vacuum Conditions

Abstract

Abstract. The possibility of creating vacuum robotics based on the polymer structures irradiated by an electron beam, in particular, polymer fibers, which provide high functional flexibility and a variety of states, is discussed. The possibility of using polymer fibers as different types of MEMS-like electromechanical elements is demonstrated - from elastic cantilevers to springs that change their state under the electron beam. Experimentally proved the presence of different functional types of fibers, correlating with their thickness, as well as the phenomenon of the fiber break. A number of exotic forms of dynamics have been demonstrated and a method for their detection has been developed using 2D Fourier spectra, integral spatial characteristics, time resolved correlograms and wavelet transforms (visualized as the scaleograms / scalograms). Access barcodes for the full video records of the corresponding experiments are provided.

Reaction-diffusion effects and spatiotemporal oscillations under SEM, STM and AFM-assisted charging in fiber-like and wire-like systems: From molecular and quantum wires to cooperative ferroelectric nanofibers and microfibers

“…Figures 1 and 2 show dielectric charging of ferroelectric polymer fibers taking into account the action of the electric double layer [122,123] . The discrete and pulsating kinetics of the charge wandering along the fiber is observed, which corresponds to the reaction-diffusion model with the wandering waves.…”

From desolvation-induced self-organization on the MALDI anchor target chip surfaces to laser-induced self-organization in MALDI techniques: Correlation-spectral analysis and complex wavelet analysis of tesiographic spots on the anchor chips

“…This complex was developed at the POI FEB RAS by the group of Fishchenko and Goncharova [62][63][64][65] . It is based on the FFTW library and was previously used for various tasks [66][67][68][69][70][71][72] . This technique of comparative Fourier measurements was named correlation-spectral analysis by the authors of the software package themselves.…”
