We all know that converting the Sun's energy into useful electricity can help in the sustainable development of nations with transitional economies. But these are large scale installations. Can photovoltaic technology, which is responsible for converting the Sun's energy to electricity, be used for generating milli or even microwatts of power? This is the power typically needed for wearable and implantable electronic devices. Such devices can be used to monitor vital human signs, such as blood pressure, temperature... etc. In our group within the microelectronics lab, we have been looking into using tiny PV cells for powering implantable electronic devices. Some of our findings are available here: https://doi.org/10.1109/JERM.2019.2937970

Contact lenses have evolved enormously during the past two decades. Their uses have shifted from ordinary vision correction platforms to wearable sensing devices. They are now being called “Smart” or “Electronic” contact lenses. They have certainly featured a great deal in many Hollywood movies, such as “Mission Impossible: Ghost Protocol” and “Minority Report”. They have also featured in two different Black Mirror episodes.

These clever devices can soon become a reality. In our group, we have just developed a proof of concept contact lens that can be used as a healthcare platform. The aim is to use this lens for monitoring vital human signs. So far, we have demonstrated the successful integration of antennae on a curved PDMS substrate.

Aarhus University, Denmark August 2018

In today's blog, I would like to share the experience of being a student at Aarhus University and living in Denmark for six months as part of the Ph.D. program. In August 2018, I was lucky enough to be given a chance to take part in a research exchange program and join the Integrated Circuit and Electronics (ICE) LAB. My advisor Dr. Hadi Heidari discussed the possibility of me joining them for three months prior to August at the ISCAS conference in Florence, Italy. When I heard about it, I wasn’t too convinced that it would be possible due to the visa process and my housing arrangements in Glasgow. Long story short, luckily, things went well and I had managed to arrange all of it. The moment when I realised I had a green light to go, it was exciting for me. This is because in my research group not a lot of people are working on circuits, and in ICE LAB almost everyone is circuit and system designer. It was a great opportunity for me to be part of the community that is experienced in circuit design. Moreover, as a student who holds a Tier4 visa in the UK, it was a huge chance for me to explore EU countries during weekends as usually, I would need to apply for a visa to do so. Little did I know, at the end of the six months I had hardly left Aarhus city itself, let alone going around Europe. Why? The following are reasons why I enjoyed myself a little too much in Aarhus, without any regrets.

Our team of four undergraduate students from various engineering disciplines participated in IEEE’s 4th student design competition 2019-2020. IEEE Circuit and Systems Society (CASS) allows undergraduate students to propose and execute Electrical Engineering related projects. The key aim of this project was to find a solution to a real-life problem using circuits and systems. Our team is from region 8 (Europe, Africa, and the Middle East) and has progressed to the second stage of the competition which takes place at the regional level. In order to compete at the international level, one team from each region will progress to the finale.

On December 2nd-6th, three members of the meLAB who are currently working as part of the Horizon 2020 project Hybrid Enhanced Regenerative Medicine Systems (HERMES) attended the first annual consortium meeting at Istituto Italiano di Tecnologia (IIT), Genoa, Italy. Over the course of five days, each team presented their work from the first twelve months, and laid out their plans for future efforts. Vahid and Rupam, two of our post-doctoral researchers, attended all five days, including the Advisory Board meeting and Eve, a PhD student, attended four days of group presentations.
