Harvesting biomechanical energy in vivo is an important route obtaining sustainable electric for powering implantable medical devices. Here, we demonstrate innovative triboelectric nanogenerator (iTENG) harvesting. Driven by the heartbeat of adult swine, output voltage and corresponding current were improved factors 3.5 25, respectively, compared with reported performance conversion In addition, evaluation iTENG was demonstrated over 72 h implantation, during which generated electricity...
Piezoelectric biomaterials are intrinsically suitable for coupling mechanical and electrical energy in biological systems to achieve vivo real-time sensing, actuation, electricity generation. However, the inability synthesize align piezoelectric phase at a large scale remains roadblock toward practical applications. We present wafer-scale approach creating biomaterial thin films based on γ-glycine crystals. The film has sandwich structure, where crystalline glycine layer self-assembles...
Stretchability is an essential property for wearable devices to match varying strains when interfacing with soft tissues or organs. While piezoelectricity has broad application potentials as tactile sensors, artificial skins, nanogenerators, enabling tissue-comparable stretchability a main roadblock due the intrinsic rigidity and hardness of crystalline phase. Here, amino acid-based piezoelectric biocrystal thin film that offers tissue-compatible omnidirectional unimpaired reported. The was...
Abstract Treating vascular grafts failure requires complex surgery procedures and is associated with high risks. A real‐time monitoring system enables quick reliable identification of complications initiates safer treatments early. Here, an electric fieldassisted 3D printing technology developed to fabricate in situ‐poled ferroelectric artificial arteries that offer battery‐free blood pressure sensing occlusion capability. The functional artery architecture made possible by the development a...
Uninterrupted, efficient power supplies have posed a significant hurdle to the ubiquitous adoption of wearable devices, despite their potential for revolutionizing human‒machine interactions. This challenge is further compounded by requirement these devices supply dependable energy data-intensive sensing and transmission. Traditional thermoelectric solutions fail deliver satisfactory performance under conditions extremely low voltages. Here, we present novel solution generator integrated...
Cellulosic materials are attractive candidates for nature piezoelectrics. Vertically aligned cellulose nanocrystal (CNC) films expected to show strong piezoelectricity as the largest dipole moment in CNCs exists along chain. In this work, we adapted confinement cell technology that was used fabricate colloidal opal structures align CNC rods vertically on a large scale. The high interfacial energy between CNC-poly(tetrafluoroethylene) (PTFE) surface and torque induced by shear force led...
Three-dimensional (3D) ferroelectric materials are electromechanical building blocks for achieving human-machine interfacing, energy sustainability, and enhanced therapeutics. However, current natural or synthetic cannot offer both a high piezoelectric response desired mechanical toughness at the same time to meet practicality. Here, lamellar metamaterial was created with ceramic-like property bone-like fracture through low-voltage-assisted 3D printing technology. The one-step printed bulk...
The liquid-solid contact electrification was used as a sensing mechanism to analyze liquid chemicals, which may eventually become new molecule analytic principle.
Wireless and passive bioelectronic medicines mimic the biological cues of extracellular matrix.
An artificial organic/inorganic composite protecting film for lithium metal anode with one-side surface pits structure was prepared by poly(vinylidene fluoride-co-hexafluoropropylene) and Al2O3+LiNO3 inorganic additives. Due to the unique structure, can not only serve as an protective film, but also act additional plating host, which synergistically enabled adapt high current densities meanwhile maintain dendrite-free during long-term cycling. As a result, protected operate stably 1000 h at...
