Smart microrobots adapt to their surroundings

Scientists at EPFL and ETH Zurich have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.

The stiffest 3D printed structures

Researchers have developed and manufactured a family of architectures that maximises the stiffness of porous lightweight materials. It's practically impossible to develop stiffer designs.

Can an "impossible object" be 3D printed, even impossibly small?

The answer is: Yes, if you take an impossible object design and combine it with micro 3d printing technology. A metallic impossible object at the size of a red blood cell is born.

The next step for 3D printing

Researchers have developed a bioinspired approach to 3D print recyclable materials using cheap desktop printers that outperform state-of-the-art printed polymers and rival the highest performance lightweight materials. This will finally enable the manufacturing of complex parts that mimic natural structural designs on the mass market.

Research helps make buses smarter

A rather unusual trolleybus has been navigating the streets of Zurich in recent months. With its large windscreen and covered wheels, it could easily be mistaken for a tram. It ­features a hybrid electric drive system that allows it to draw power from an on-board traction battery as well as ­overhead wires. But this bus is also "smart", boasting specially designed software that automatically gathers information on the route.

Capturing brain signals with soft electronics

A new technology for long-term stable neural recording. It is based on a novel elastic material composite, which is biocompatible and retains high electrical conductivity even when stretched to double its original length.

Rotational 3D printing technique yields high-performance composites

Nature has produced exquisite composite materials—wood, bone, teeth, and shells, for example—that combine light weight and density with desirable mechanical properties such as stiffness, strength and damage tolerance.

Roads Generate Electricity for Even the Toughest Tasks

A solar roof on a road will make twice as much electricity per unit area compared to a solar road and be more easily upgraded to affordable higher efficiency PV as it becomes available.

When solar-powered drones meet Arctic glaciers

Solar-powered flying platforms have yet to prove their real-world applicability outside of targeted demonstrations. Monitoring glaciers in polar regions is in pole position to become a primary application, as the midnight sun offers ideal conditions for perpetual flights.

3-D-printed minifactories

There will soon be nothing that cannot be produced with 3D printing. However, the materials used for this process are still "dead matter" such as plastics or metals.

Ultra-thin concrete roof with thin-film photovoltaics

A prototype for an ultra-thin, sinuous concrete roof using innovative design and fabrication methods. A second, exterior layer of the concrete sandwich structure encloses the roof, onto which thin-film photovoltaic cells are installed.

World record solar cells for "move"

Swiss start-up Flisom is ready for the global market: the company, a spin-off from ETH Zürich and Empa, has developed a unique roll-to-roll process for the cost-effective production of flexible and highly efficient thin-film solar modules.

SwissKitePower Project Switzerland

The SwissKitePower project is a multidisciplinary research and development effort aimed at creating a totally new device which can harness wind energy at high altitudes. The winds at altitude are stronger and more consistent than those at the ground and represent an enormous potential source of renewable energy.

Improving understanding of the quantum world with quantum dots

Quantum behaviour plays a crucial role in novel and emergent material properties, such as superconductivity and magnetism. Unfortunately, it is still impossible to calculate the underlying quantum behaviour, let alone fully understand it.
