Bovine pericardium (BP) has been used as leaflets of prosthetic heart valves. The are sutured on metallic stents and can survive 400 million flaps (~10-year life span), unaffected by the suture holes. This flaw-insensitive fatigue resistance is unmatched synthetic leaflets. We show that endurance strength BP under cyclic stretch insensitive to cuts long 1 centimeter, about two orders magnitude longer than a thermoplastic polyurethane (TPU). results from high collagen fibers soft matrix...
Achieving tough and stable tissue adhesion under a physiological environment is of great significance for the clinical applications hydrogel adhesives. The current adhesives face challenges in preservation maximal long time due to swelling. Here, we propose double-network strategy by with long-term stability environment. A consisting covalently crosslinked primary network tunable hydrophilicity non-covalently secondary functional groups designed. exhibited hydrophobicity environment, which...
Bio/ecoresorbable electronic systems create unique opportunities in implantable medical devices that serve a need over finite time period and then disappear naturally to eliminate the for extraction surgeries. A critical challenge development of this type technology is materials can as thin, stable barriers surrounding ground water or biofluids, yet ultimately dissolve completely benign end products. This paper describes class inorganic material (silicon oxynitride, SiON) be formed thin...
Due to the incorporation of magnetic nanoparticles (MNPs), magnetically tuneable hydrogels have attracted considerable attention recently due their ability undergo remotely controlled large deformation. This work investigates mechanics deformation from thermodynamics perspective for magneto-thermal sensitive hydrogels. The chemical a temperature gel is first recapped before moving on magnetism. Furthermore, an explicit energy form hydrogel adopted. proposed field theory implemented in finite...
Patterned magnetic hydrogels have been fabricated by ion transfer printing and their magnetothermal behavior has characterized.
Biomineralization occurs in natural organisms, such as bones, teeth, shells and tendons. The formation mechanism mechanical properties have been extensively studied for mineralized hard tissues, especially bone teeth. However, the research on evolution of soft tissues remains challenging due to long period mineralization. Here we use polymer-induced liquid-precursor (PILP) method achieve accelerated vitro mineralization bovine pericardium with SrCO3. modulus, tensile strength, toughness,...
Synthesizing perceivable artificial neural inputs independent of typical sensory channels remains a fundamental challenge in the development next-generation brain-machine interfaces. Establishing minimally invasive, wirelessly effective, and miniaturized platform with long-term stability is crucial for creating clinically meaningful interface capable mediating perceptual feedback. In this study, we demonstrate fully implantable wireless transcranial optogenetic encoder designed to generate...
