Entanglement

As economy relies more and more on digital transactions their security becomes more and more important. PKC, Public Key Cryptography, is the leading technology for ensuring transaction security. It was invented in 1976 and it is based on the complexity of finding the factors in a very large number. Even the …

The donkey hat is evolving …

Not sure if this heading makes any sense to you… When I went at the primary school (that was eons ago) and I failed a test sometimes the teacher would place a "donkey hat" on me. The hat was a paper cone with a writing on it saying "Somaro", that …

Creating nanoscale patterns for secure Id

Creating a secure identification for the many products being sold remains a challenge. You want to have a secure identity, impossibile to duplicate, and you also want to have it cheap so that it can really be used.  There is basically nothing that cannot be reproduced, but the point is …

The “clinical” eye…

There is a growing number of easy to perform tests detecting a variety of conditions that can be taken at home or in areas without specific medical assistance. They are based on the analyses of a body fluid, like saliva, blood or urine, performed by a small strip of paper …

Talking about flexible electronics…

Just yesterday I posted a news on the creation of a stretchable and bendable antenna and I mentioned that it represents an important component in wearable electronics. These latter have been improved considerably resulting in circuits on a plastic substrata that can be easily bended. The "density" of these "plastic …

I’ve got a new antenna in my wrist band

Sensors keep evolving extending their range of application. One area where lot of work is going on is the one of body sensors to track our health status. They can be used to monitor pathological conditions, the body reaction to a cure or to a truing session. In particular a lot …

A connected World … inside

Scientists are at work, both in Europe and in the US, to understand the Brain. There are different approaches to do that, and there is also a lot of debate on the validity of each, as there were (and still are) many on the kind of knowledge that can be …

I’ve got to program my geranium…

Ever heard of plant nanobionics? Neither had I. I stumbled on it reading a report by MIT Technology Review on Bionic Plants. A team of researchers at MIT have managed to boost the capability to harvest light and producing electrons by 30% by embedding carbon nanotube in the chloroplasts. Additionally, they have shown how it …

Being serious about IoT

Yesterday I had the opportunity of visiting Wuxi, China, and meeting with several Telecommunications Companies, with a few industries and representatives of the Jiangnan University, and visiting the Research Centre on Internet of Things, 2,000 researchers strong.  I learnt that the Chinese Government has decided in 2009 to appoint Wuxi as the …

Replacing electrons with photons

We have available an amazing transportation capacity through optical fibre, trillions of bits per second and more. The limits are actually far higher but we are constrained by the electronic-photonic transformation process. Today electronics can reach 40 Gbps in the conversion from electrons through photons via a laser and these laser are, …
