Graphene-based Wearables for Health Monitoring, Food Inspection and Night Vision

Graphene-enabled fitness band measures heart rate, hydration, oxygen saturation, breathing rate and temperature. The technology will be showcased at MWC19.

Scientists have developed dozens of new graphene-based prototypes. These technologies aim to turn mobile phones into life saving devices. The first of ICFO’s devices on display will allow customers to monitor their level of exposure to sunlight through a UV sensor. Designed as a flexible, transparent and disposable patch, it connects to a mobile device and alerts the user once he or she has reached a defined threshold of sun exposure.

Using the same core technology as the UV patch, ICFO’s fitness band is being developed to measure heart rate, hydration, oxygen saturation, breathing rate and temperature, while monitoring the use...

Developable Mechanisms can Reside inside the Surface of a Structure

It took just over 10 years, but real science has finally caught up to the science fiction of Iron Man’s transforming exoskeleton suit. Engineers at Brigham Young University detail new technology that allows them to build complex mechanisms into the exterior of a structure without taking up any actual space below the surface.

This new class of mechanisms, called “developable mechanisms,” get their name from developable surfaces, or materials that can take on 3D shapes from flat conformations without tearing or stretching, like a sheet of paper or metal...

Highly durable aerogel could ultimately be an upgrade for insulation on spacecraft. UCLA researchers and collaborators at eight other research institutions have created an extremely light, very durable ceramic aerogel. The material could be used for applications like insulating spacecraft because it can withstand the intense heat and severe temperature changes that space missions endure.

Ceramic aerogels have been used to insulate industrial equipment since the 1990s, and they have been used to insulate scientific equipment on NASA’s Mars rover missions...

The 1st Walking Robot that Moves Without GPS

Desert ants are extraordinary solitary navigators. Researchers were inspired by these ants as they designed AntBot, the first walking robot that can explore its environment randomly and go home automatically, without GPS or mapping. This work opens up new strategies for navigation in autonomous vehicles and robotics.

Human eyes are insensitive to polarized light and ultraviolet radiation, but that is not the case for ants, who use it to locate themselves in space. Cataglyphis desert ants in particular can cover several hundreds of meters in direct sunlight in the desert to find food, then return in a straight line to the nest, without getting lost...
