An artificial muscle built from a sandwich of soft, stretchable elastomers and carbon nanotubes electrodes. This type of actuator could be used in everything from wearable devices to soft grippers, laparoscopic surgical tools, entirely soft robots or artificial muscles in more complex robotics.

In the Eko-Viikki housing area in Helsinki, Finland, nine properties have been equipped with solar heating systems for producing heat for water heating systems and, in a few of the houses, for underfloor heating. From the solar panels, the accumulated heat is conducted to an insulated water tank functioning as a thermal storage. Credit: Helen

By transitioning to solar photovoltaics (PV) in the US, up to 51,999 American lives would be saved at $1.1 million invested per life.

Scientists are exploring ways to develop transparent or semi-transparent solar cells as a substitute for glass walls

The stretchable batteries were printed on fabric for this demonstration. They make up the word NANO on the shirt and are powering a green LED that is lit in this picture.

Each fingertip pressure sensor mounted on this glove is connected to an LED. The intensity of the LEDs varies according to the pressure applied by the fingertips. The glove makes it possible to ascertain degrees of pressure that are difficult to obtain just by examining images. Credit: 2017 Someya Group, The University of Tokyo. A

The new camera was developed for filming chemistry and physics occurring at extreme speeds. Credit: Image courtesy of Lund University Forget high-speed cameras capturing 100,000 images per second. A research group at Lund University in Sweden has developed a camera that can film at a rate equivalent to five trillion images per second, or events

This is the water harvester built at MIT with MOFs from UC Berkeley. Using only sunlight, the harvester can pull liters of water from low-humidity air over a 12-hour period.

Paul J.D. Whiteside demonstrates the sonoillumination waveguide device. Credit: Ryan Owens, MU College of Engineering The first laser treatments used to treat skin conditions such as benign vascular birthmarks and port-wine stains were developed more than 40 years ago. Since then, clinicians and dermatologists have seen a rise in demand for minimally invasive laser-based treatments,
