Printing flexible wearable electronics for smart device applications

Credit: Wei Wu s group WASHINGTON, June 10, 2021 The demand for flexible wearable electronics has spiked with the dramatic growth of smart devices that can exchange data with other devices over the internet with embedded sensors, software, and other technologies. Researchers consequently have focused on exploring flexible energy storage devices, such as flexible supercapacitators (FSCs), that are lightweight and safe and easily integrate with other devices. FSCs have high power density and fast charge and discharge rates. Printing electronics, manufacturing electronics devices and systems by using conventional printing techniques, has proved to be an economical, simple, and scalable strategy for fabricating FSCs. Traditional micromanufacturing techniques can be expensive and complex.

Combining biochemical and topographical cues improves quality of skeletal muscle regeneration

Combining biochemical and topographical cues improves quality of skeletal muscle regeneration When trauma, illness, or injury causes significant muscle loss, reconstructive procedures for bioengineering functional skeletal muscles can fall short, resulting in permanent impairments. Finding a synergy in the importance of biochemical signals and topographical cues, researchers from Wake Forest Institute for Regenerative Medicine, Sungkyunkwan University, and Chonnam National University developed an efficient technique for muscle regeneration and functional restoration in injured rats. They describe results from the technique in the journal Applied Physics Reviews, from AIP Publishing. The group expanded on a method they previously developed using muscle-specific materials derived from an organism s tissues (dECM-MA) to construct bioinks, which are materials used for 3D-printing tissue.
