Stretchable ionic conductors with high transparency and excellent resilience are highly desired for flexible electronics, but traditional conductive hydrogels easy to dry freeze. Herein, a newly hybrid crosslinking strategy is presented preparing stretchable transparent hydrogel by using sodium alginate (SA) acrylamide based on the unique physically covalently mechanism, which transformed into ...

Abstract Ultrathin, breathable, and skin‐compatible epidermal electronics are attractive for wearable implantable healthcare biomedical applications. However, materializing integrating all electronic components on ultrathin platforms is still challenging. Here, a charge‐storing tattoo (E‐tattoo) device with ultrathin, properties reported. Silk protein nanofibers (SNFs) carbon nanotubes (CNTs) f...

Abstract This study demonstrates a cost-effective portable fabrication system for 3D printing complex structures from polydimethylsiloxane (PDMS). Material development and characterisation allowed the design production of printer that is capable fabricating PDMS using photo-initiator LED curing process. A model participant’s ear was captured handheld scanner. These data were used to directly pr...

3D objects with integrated electronics are produced using an additive manufacturing approach relying on multiphoton fabrication (direct laser writing, (DLW)). Conducting polymer-based structures (with micrometer-millimeter scale features) printed within exemplar matrices, including elastomer (polydimethylsiloxane, (PDMS)) have been widely investigated for biomedical applications. The fidelity o...

A s those haunting dreams of failing an exam start to fade, older Americans are heading back to school. As many as 50% of enrolled students are now classified as " those returning to education, " according to research at the University of Missouri-Rolla. This trend makes perfect sense to Guruprasad Madhavan, who, following basic engineering training in instrumentation and control systems and gr...

Hard magnetic materials belong to a novel class of soft active with the capability quick, large, and complex deformation via applying an external actuation. They have extensive range potential applications in robots, biomedical devices, stretchable electronics, etc. Recently, investigation on experimental theoretical nonlinear mechanics hard cantilevers has received notable considerations. In a...

carbon nanotubes (cnts) are high aspect ratio allotropes of carbon. because of their unique physical and chemical characteristics, they are nominated for a vast variety of applications in the biomedical field. their very low solubility is the only problem of them which is solved by different methods of functionalization. after discoveries in the last few years of the capacity of cnts to penetra...

purpose: the distinction between the concepts of science and technology has made it necessary for economic and scientific policymakers to know the realms of these two areas. the relationship between the science and the technology is changing and also is variable depending on the circumstances, scientific areas, and from one time to another one. the current research aims at studying the growth t...
