Abstract Background Increasing antibiotic resistance continues to focus on research into the discovery of novel antimicrobial agents. Due its and wound healing-promoting activity, metal nanoparticles have attracted attention for dermatological applications. This study is designed investigate scope bactericidal potential zinc ferrite (ZnFe 2 O 4 NPs), mechanism anti-bacterial action along with cytocompatibility, hemocompatibility, healing properties. Results ZnFe NPs were synthesized via a...
Abstract Infants are physically vulnerable and cannot express their feelings. Continuous monitoring measuring the biomechanical pressure to which an infant body is exposed remains critical avoid injury illness. Here, a area sensor network comprising edible triboelectric hydrogel sensors for all‐around motion reported. Each soft holds collection of compelling features high signal‐to‐noise ratio 23.1 dB, sensitivity 0.28 V kPa −1 , fast response time 50 ms. With assistance deep learning...
The high moisture level of exhaled gases unavoidably limits the sensitivity breath analysis via wearable bioelectronics. Inspired by pulmonary lobe expansion/contraction observed during respiration, a respiration-driven triboelectric sensor (RTS) was devised for simultaneous respiratory biomechanical monitoring and acetone concentration analysis. A tin oxide-doped polyethyleneimine membrane to play dual role as both layer an sensing material. prepared RTS exhibited excellent ability in...
Interfacing with the human body, wearable and implantable bioelectronics are a compelling platform technology for healthcare monitoring medical therapeutics. However, clinical adoption of these devices is largely shadowed by their weakness in humidity resistance, stretchability, durability, biocompatibility. In this work, we report self-powered waterproof biomechanical sensor stretchability up to 440% using giant magnetoelastic effect soft polymer system. By manipulating magnetic dipole...
Self-sensing actuators are critical to artificial robots with biomimetic proprio-/exteroception properties of biological neuromuscular systems. Existing add-on approaches, which physically blend heterogeneous sensor/actuator components, fall short yielding satisfactory solutions, considering their suboptimal interfaces, poor adhesion, and electronic/mechanical property mismatches. Here, a single homogeneous material platform is reported by creating silver-polymer framework (SPF), thus...
Footfall contains the highest harvestable biomechanical energy from human body, which can attain 67 W, showing great potential as a pervasive and sustainable power source for wearable bioelectronics in era of Internet Things. Developing an effective technology robust efficient harvesting walking remains highly desired. Here, we present waterproof smart insole, based on triboelectric nanogenerator, harvesting. This insole was rationally designed composite structure to fully utilize pressure...
The current energy crises and imminent danger of global warming severely limit the ability to scale societal development sustainably. As such, there is a pressing need for utilizing renewable, green sources, such as wind energy, which ubiquitously available on Earth. In this work, fundamentally new wind-energy-harvesting technology reported, based giant magnetoelastic effect in soft composite system, namely, generators. Its working principle wind-induced mechanical deformation, alters...
High relative permittivity and low dielectric loss are two desired parameters of a triboelectric layer to enhance its mechanical-to-electrical energy conversion efficiency in nanogenerator (TENG). However, the elevated is always accompanied by increasing loss, limiting further improvement or even reducing electrical output. Herein, we report method for improving suppressing via nanoscale design at particle-polymer interface. When incorporated with 2 wt % Ag@C, triboelectric-layer-enhanced...
Potential multijunction application of CsPbI3 perovskite with silicon solar cells to reach efficiencies beyond the Shockley-Queisser limit motivates tremendous efforts improve its phase stability and further enlarge band gap between 1.7 1.8 eV. Current strategies increase via conventional mixed halide engineering are accompanied by detrimental segregation under illumination. Here, ethylammonium (EA) in a relatively small fraction (x < 0.15) is first investigated fit into three-dimensional...
Developing scalable electrical stimulating platforms for cell and tissue engineering applications is limited by external power source dependency, wetting resistance, microscale size requirements, suitable flexibility.
