Magnetoelectric (ME) effect experimentally discovered about 60 years ago remains one of the promising research fields with main applications in microelectronics and sensors. However, its to biology medicine are still their infancy. For diagnosis treatment diseases at intracellular level, it is necessary develop a maximally non-invasive way local stimulation individual neurons, navigation, distribution biomolecules damaged cells relatively high efficiency adequate spatial temporal resolution. Recently developed ME materials (composites), which combine elastically coupled piezoelectric (PE) magnetostrictive (MS) phases, have been shown yield very strong effects even room temperature. This makes them toolbox for solving many problems modern medicine. The materials, processing technologies, as well most prospective biomedical will be overviewed, trends using future therapies, wireless power transfer, optogenetics considered.

The emerging field of implantable bioelectronics has attracted widespread attention in modern society because it can improve treatment outcomes, reduce healthcare costs, and lead to an improvement the quality life. However, their continuous operation is often limited by conventional bulky rigid batteries with a lifespan, which must be surgically removed after completing missions and/or replaced being exhausted. Herein, this paper gives comprehensive review recent advances nonconventional energy solutions for bioelectronics, emphasizing miniaturized, flexible, biocompatible, biodegradable power devices. According source energy, promising alternative are sorted into three main categories, including storage devices (batteries supercapacitors), internal energy-harvesting (including biofuel cells, piezoelectric/triboelectric harvesters, thermoelectric biopotential generators), external wireless transmission technologies inductive coupling/radiofrequency, ultrasound-induced, photovoltaic devices). Their fundamentals, materials strategies, structural design, output performances, animal experiments, typical biomedical applications also discussed. It expected offer complementary sources extend battery lifetime while acting as independent supply. Thereafter, existing challenges perspectives associated these powering outlined, focus on bioelectronics.

Abstract Triboelectric nanogenerators (TENGs) have gained significant traction in recent years the bioengineering community. With potential for expansive applications biomedical use, many individuals and research groups furthered their studies on topic, order to gain an understanding of how TENGs can contribute healthcare. More specifically, there been a number focusing implantable triboelectric (I‐TENGs) toward self‐powered cardiac systems In this review, progression cardiovascular healthcare, including monitoring devices, therapeutic power sources pacemakers, will be systematically reviewed. Long‐term expectations these TENG devices through biocompatibility other utilization strategies also discussed.

The advent of implantable bioelectronic devices offers prospective solutions toward health monitoring and disease diagnosis treatments. However, advances in power modules have lagged far behind the tissue-integrated sensor nodes circuit units. Here, we report a soft system that monolithically integrates wireless energy transmission storage modules. unit comprises biodegradable Zn-ion hybrid supercapacitors use molybdenum sulfide (MoS2) nanosheets as cathode, ion-crosslinked alginate gel electrolyte, zinc foil anode, achieving high capacitance (93.5 mF cm-2) output voltage (1.3 V). Systematic investigations been conducted to elucidate charge mechanism supercapacitor assess biodegradability biocompatibility materials. Furthermore, wirelessly transmitted can not only supply directly applications but also ensure constant, reliable output. Its capabilities successfully demonstrated for controlled drug delivery.

Nowadays, wireless sensor networks are becoming increasingly important in several sectors including industry, transportation, environment and medicine. This trend is reinforced by the spread of Internet Things (IoT) technologies almost all sectors. Autonomous energy supply thereby an essential aspect as it decides flexible positioning easy maintenance, which decisive for acceptance this technology, its wide use sustainability. Significant improvements made last years have shown interesting possibilities realizing energy-aware nodes (WSNs) designing manifold highly efficient converters reducing consumption hardware, software communication protocols. Using only a few these techniques or focusing on one not sufficient to realize practicable market relevant solutions. paper therefore provides comprehensive review system design battery-free WSN, making ambient transmission. It addresses strategies gives deep insight management methods well saving node network level. The aim provide into increase awareness suitable nodes.

Implantable bioelectronic devices are becoming useful and prospective solutions for various diseases owing to their ability monitor or manipulate body functions. However, conventional implantable (e.g., pacemaker neurostimulator) still bulky rigid, which is mostly due the energy storage component. In addition mechanical mismatch between rigid device soft human tissue, another significant drawback that entire should be surgically replaced once initially stored exhausted. Besides, retrieving physiological information across a closed epidermis tricky procedure. wireless interfaces power data transfer utilizing radio frequency (RF) microwave offer promising solution resolving such issues. While RF interfacing extensively investigated developed using electronics, application bioelectronics challenge constraints requirements of in vivo environments, as softness, small module size, tissue attenuation, biocompatibility.
