Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

HYSTERESIS OF BLOOD DIELECTRIC CHARACTERISTICS - TEMPERATURE RELATIONSHIP

open access: yesRussian Journal of Biotherapy, 2015
The paper presents the results of the study of dielectric blood characteristics - 20% solution of human albumin, 40% solution of glucose and 0,9% solution of NaCl, at the temperature ranging from 30 to 42 °C and the frequency of 0,6 GHz. At 37 °C the blood and albumin showed an abrupt increase in absorption.

Bio‐Inspired Artificial Ionic Mechanoreceptor

open access: yesAdvanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,
