Jellyfish-inspired electronic skin glows when it gets hurt

Thu, 2017-11-02 01:38
Electronic-skin technologies for prosthetics and robots can detect the slightest touch or breeze. But oddly, the sensors that make this possible do not respond effectively to a harmful blow. Now researchers report the development of a jellyfish-inspired electronic skin that glows when the pressure against it is high enough to potentially cause an injury.

Folding circuits just atoms thick using the principles of origami

Wed, 2017-11-01 22:35

Gradation-tint smart window

Mon, 2017-10-30 19:26
Scientists have developed smart glass capable of producing various shades on its surface. Unlike the conventional types, the newly developed tinting smart glass allows users to easily change the shaded area of a window. For example, a user would be able to change the shaded area of a window in accordance with the elevation of the sun. The technology may be applicable to various types of windows, including those of automobiles and buildings, enabling them to offer both shade and clear visibility simultaneously.

Envisioning a new engineering field: Understanding atomic-scale patterns

Fri, 2017-10-27 00:52
