Tiny fuel cells convert sweat to electricity that can power sensors in electronic skin. Yu et al., Sci. Robot. 5, eaaz7946 (2020)

A smart second skin gets all the power it needs from sweat

Lightweight, flexible materials can be used to make health-monitoring wearable devices, but powering the devices is a challenge. Using fuel cells instead of batteries could make the difference.

Big questions about risk assessment of nanomaterials

We need to carefully assess nanomaterials to ensure their safety, but there are questions over whether the existing practice of risk assessment is up to the task.

Engineering’s unexpected and microscopic beauty

We all know engineering is useful, functional, even ingenious. But the engineering photography competition we hold each year provides us a chance to wander outside its merely utilitarian aspects into dimensions…

New uses for carbon nanotubes

University of California, Riverside, scientists have added ionic liquid to single-walled carbon nanotubes and modified the…

Power to you: carbon nanotube muscles are going strong

Just on a year ago my colleagues and I announced our discovery that carbon nanotube yarns could be made to twist and rotate at great speeds when electrically stimulated. In this way we had created “artificial…

New sponge to clean up oil spills

A new type of carbon nanotube sponge can absorb over 100 times its weight in oil making it perfect for cleaning up oil spills…

Going up! The elevator that could take you into space

A major Japanese construction company, Obayashi Corporation, has announced plans to build a space elevator within 40 years, allowing people to be transported to space stations above the earth. The proposed…
