Creating camouflage with artificial skin

Scientists at Bristol University are reported to have created artificial skin that can mimic the chromatophores of the squid and change to camouflage it from its surroundings. The skin been...

Nonlinear optical metamaterials

A nonlinear material that has opposite refractive indices at the fundamental and harmonic frequencies of light has been observed by researchers at Georgia Institute of Technology.  Such an...

New metal addition to SMA makeup

I see that that tried and trusted combination of nickel and titanium to provide shape memory alloys that find their way into all sorts of application from stents in healthcare to actuation in...

Trees are source for high-capacity, soft batteries

A method for making elastic high-capacity batteries from wood pulp was unveiled by researchers in Sweden and the US. Using nanocellulose broken down from tree fibres, a team from KTH Royal...

The global race in developing metamaterials

 read in the Chinese press, the People's Daily, that China is leading the way in developing metamaterials for use in a wide variety of applications including communications and aerospace....

Some biomimetics for windows

I like biomimetics, if only because we think that we invent new ideas and find out that nature has always beaten us to it. When you combine this with the need for windows that can shade and cool...

2D Materials for flexible electronics

There is a need for lighter and more flexible electronics for applications like defence and security where personnel are required to carry a challenging level of electronics in order to do their...

Low cost OLED's for smart packaging

A Finnish company, VTT, have developed a low cost roll-to-roll OLED technology, that uses electroluminescence and semiconductors to generate light,  that could be used for packaging. The...

Smart packaging to detect spoiled meat

We are seeing more reports of sensors for smart packaging that can detect the freshness of products. With meat there are volatile compounds given off when it starts to putrefy, specifically...

Smart materials for smart products

I see that the Fraunhofer Institutes are getting some press coverage on their ability to develop new materials for new electronic applications. The interesting thing about this is that some are...

Magneto-Mechano-Electric generation for MEMS

Low-power consumption devices such as MEMS based sensors and health monitoring devices require energy sources that can recharge or replace the small batteries that power them. Energy harvesting...

Modelling complex auxetic systems

Metamaterials continue to intrigue us as they display properties that are not typically obvious in nature and none more so than auxetics, those materials that are counterintuitive and expand...

Controlling elastic waves with metamaterials

The University of Missouri is reporting the sensing of subwavelength acoustic and elastic waves with metal surfaces engraved with chiral patterns created with a laser. The material is however...

The Future of Metamaterials and Metasurfaces

I took part in a webinar the other day that covered the current state of technology associated with optical metamaterials as delivered by leading researchers: ·     ...

Energy harvesting metasurfaces

I'm sure that we've all heard of metamaterials, my definition being  a heterogeneous material that exhibits extraordinary properties arising from the combination of its structure and its...

Smart Materials Competition - Scoping Report

Innovate UK announced a new competition in February about "Creating Smart products from Smart Materials". In the time leading up to the release of the details of the competition and its...

Colour changing camouflage

Anything relating to camouflage is usually a hot topic as we are all fascinated as to the natural world and how some creatures are able to control the colour in their skins in order to "blend...

Self-healing concretes with shape memory!

I couldn't resist the title of this article that I found as I'd been wondering about the use of shape memory technology in the built environment for a while after reading a snippet somewhere...

Superhydrophobic coatings

Having just written about superhydrophobics in nature (with the gecko) I now see that UCL have been busy in developing superhydrophobic coatings that can be applied to a range of surfaces...

Superhydrophobics as basis for self cleaning surfaces

I've written about superhydrophobics before but this note is about something other than lotus leaves of the feet of geckos, however it does relate to geckos and the minute spines they have on...
