Scientists from Immanuel Kant Baltic Federal University found out that polymeric coating enables to improve the structure and properties of magnetoelectric composites, that are used in medicine for drug delivery and also in creation of implants and tissues. Thus, modification with polymer helps equal distribution of composite’s components, and also enhances its piezoelectric properties by 40%.
In a significant leap for aerospace and mechanical engineering, researchers have developed a cutting-edge bidirectional energy-controlled piezoelectric shunt damping technology. This breakthrough not only significantly enhances the suppression of vibration amplitudes in mechanical systems without external power but also harnesses electrical energy, heralding a new era of self-powered solutions.
The cardiac pacemaker of the future could be powered by the heart itself, according to researchers in China. Current cardiac pacemakers use a battery power supply and leads to keep hearts beating regularly. Yi Zhiran and his group are investing batteryless powering and leadless pacing, harvesting kinetic energy from the heart to power the lifesaving device. The energy is harvested by the buckling of the encapsulated structure of the pacemaker, creating buckled piezoelectric energy.
The race is on to create natural biocompatible piezoelectric materials for energy harvesting, electronic sensing, and stimulating nerves. Researchers decided to explore peptide-based nanotubes, and in the Journal of Applied Physics, they report using a combination of ultraviolet and ozone exposure to generate a wettability difference and an applied field to create horizontally aligned polarization of nanotubes on flexible substrates with interlocking electrodes. The group’s work will enable the use of organic materials more widely.
Researchers at Berkeley Lab and UC Berkeley have demonstrated that a common material can be processed into a top-performing energy storage material. Their discovery could improve the efficiency, reliability, and robustness of personal electronics, wearable technologies, and car audio systems.
A new fundamental understanding of the behavior of polymeric relaxor ferroelectrics could lead to advances in flexible electronics, actuators and transducers, energy storage, piezoelectric sensors and electrocaloric cooling, according to a team of researchers at Penn State and North Carolina State.
