Smart Windows Get Smarter (and Self-Powered)

A “smart window” from Princeton University uses a transparent solar cell to selectively absorb and harvest near-ultraviolet light. The advanced window controls the transmission of visible light and infrared heat into the building, while the new type of solar cell uses near-UV light to power the system.

Ultra-Thin Camera Says Good-Bye to the Lens

A new proof-of-concept design retires one of the most familiar parts of a traditional camera: the lens. By swapping out the glass lens with a tiny array of light receivers, a California Institute of Technology team believes the thinner, lighter model supports a new wave of ubiquitous imaging.

3D Printed Tensegrity Object Can Change Shape

A team of researchers from the Georgia Institute of Technology has developed a way to use 3D printers to create objects capable of shape change. The objects use tensegrity, a structural system of floating rods in compression and cables in continuous tension. The researchers fabricated the struts from shape memory polymers that unfold when heated. The technology could someday be used in applications ranging from space missions to biomedical devices.

Self-Learning Robot Hands Adapt to Grasp Objects

A new grasp system with robotic hands works without previously knowing the characteristics of objects. The system, which learns by trial and error, was developed by researchers at Bielefeld University in Bielefeld, Germany. It features two hands that are based on human hands in terms of both shape and mobility. The robot brain for the hands must learn how everyday objects like pieces of fruit or tools can be distinguished based on their color or shape, as well as what matters when attempting to grasp the object; for example, a banana can be held, and a button can be pressed. The system learns to recognize such possibilities as characteristics, and constructs a model for interacting with and re-identifying the object.

Crawling Robot is Powered by Moisture

Using an off-the-shelf camera flash, researchers at Jilin University, China, turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity, without the need for any external power.
