In nature, the skin of cephalopods (animals with tentacles attached to the head) exhibits unparalleled camouflage ability. Their skin contains pigment groups that can sense changes in environmental light conditions, and they ...
A common chemical reaction that most people have seen first-hand is the inspiration for a new way to make a flexible gel film that could lead to innovations in sensors, batteries, robotics and more.
Recent studies in emerging flexible humidity sensors have achieved great developments in advanced manufacturing methods, as well as innovative applications including human health care detection, plant health management and ...
Implantable bioelectrodes are electronic devices that can monitor or stimulate biological activity by transmitting signals to and from living biological systems. Such devices can be fabricated using various materials and ...
It is often desirable to restrict flows—whether of sound, electricity, or heat—to one direction, but naturally occurring systems almost never allow this. However, unidirectional flow can indeed be engineered under certain ...
Surfactants play an important role in every day life, for instance as major components in soaps. Since they feature hydrophilic and hydrophobic parts in their structure, they accumulate at water interfaces with air and can ...
Synthetic hydrogels show great promise in tissue repair, drug delivery, medical implants and many other applications. Hydrogels functionalized with electrically conductive components can be used in bioelectronic devices for ...
Miniaturized and multicolored light-emitting device arrays provide a promising instrument to sense, image and compute in materials science and applied physics. A range of emission colors can be achieved by using conventional ...
Finding a 3D printable ink that conducts electricity, yet is strong, flexible and stretchable, has been a goal of materials scientists around the world since 3D printing began, says Daeha Joung, Ph.D., an assistant professor ...
The idea of wirelessly gathering electrical information from the body through the skin is not new. However, the ideal electrode material must fulfill a significant list of criteria to be a realistic candidate for use on patients. ...
