Last week, the EIT-related startup company Acconeer got the reward "Guldmobilen" in the cathegory "Innovation of the year 2015” at the Swedish Mobile Awards Event "Mobilgalan" in Stockholm. The Acconeer innovation has been presented earlier at the EIT-website and originates from research performed at the department. It's a perfect and attractive inspirational example for those students and researchers who are interested in finding future business potential from ongoing research. 

Acconeer  have developed a microradar that opens up a new world for human interaction and future applications are envisaged in e.g. home robots, drones, surveillance or other areas where there are requirements to measure distance or detect proximity. Other fields interested in adopting Acconeer technology  are monitoring vital life signs such as breathing rate and pulse rate. The sensor’s radiowave will penetrate light material such as clothing but not skin and be able to measure breathing rate or pulse therefore it can be used for a multitude of health care and sports applications. And much more. The sky is the limit!

Mobilgalan - The Swedish Mobile Awards - turned 15 this year and have rewarded mobile innovations, products, services and companies every year since 2001. Some memorable earlier winners are King, Swish, Skype, Spotify, Minecraft, all swedish startups who have left a great footprint in global business.

EIT Congratulates Acconeer and wish all the best in future ventures!

In response to a series on "death of 5G", in IEEE ComSoc Technology News, the MAMMOET project team decided to contribute to its resurrection. Their response was well received and the Editor wrote: "After our doom laden 'death of 5G' series we did get some letters. In particular, the good people of the MAMMOET project in Europe managed to hit several points at once." Read the full story here.



Theory becomes practice in Imans research

Published: 2015-12-11

EITs latest doctor is Iman Vakili and his defense was held on November 27 this year. In his research they deal with so-called wavelets and short pulses of 100 ps. During this ultrashort time, 60 GHz signals are sent into the wideband antenna that Iman is behind .

Small and efficient short range antennas

The research area has, to some extent, already made an entry into commercial applications. The EIT-originated venture Acconeer is an example of an adopter of this kind of technology in order to make robotic vacuum cleaners work. This is an area where cost-effective short range radar functionality will be needed. In the long term this technology will climb up the frequency-ladder to perhaps 200 GHz in similar and other applications. These extremely high frequencies are already on the researchers' agenda whereby you can achieve even shorter pulses and higher resolutions.

-A specifically sized bluetooth-antenna would, redesigned for 60GHz, give much, much higher gain, says Iman . We get smaller antennas for higher frequencies simply. Antenna size is related to the wavelength, a fact known by all electrical engineers.

60 GHz is extremely suitable for indoor applications. Even if higher frequencies might decrease the range, it could still enable wireless contacting of backplanes, replacement of cables inside computers, etc. As for the bit rate we are talking about up to 20 gigabits per second in future applications. -Something we already can accomplish in a laboratory environment, says Iman.

Collaboration between research groups

Iman cooperates with Lars-Erik Wernerssons group where Lars-Erik himself is a supervisor making this a really good example of cross fertilization between EIT-units.

The wavelet-generator that Iman uses is designed by the nano-group and the antenna that he designed is extremely wide band because the transmitted pulse is very short. Remember the Dirac pulses containing all frequencies because it was infinitely short? Iman works really at the border between theory and practice and has in his research project combined the wavelet generator and an antenna into a functioning system .

Attracted to research. But perhaps in industry.

With all respect to vacuum cleaners, Imans research can be used for other things also. For example, security personnel at an airport might want to see through clothes and quickly uncover the introduction of illegal things into safe areas. Looking ahead, Iman wants to do research with a useful and practical extension in products or industrial applications. A wide field as it appears. -Lately, however, all the focus has been on the thesis and the dissertation so I need to recover a bit before the next step towards the future is taken, Iman tells us.

Started as a summer project

Iman arrived in Lund 2009 and started in a summerproject within Mats Gustafssons Teorel-group 2010. A project that grew to a master thesis work and the materialized further to a research project finanzed by the nano-group. To learn by teaching others is a method also used by Iman in providing lecturing-efforts within the Teorel courseplan.

Iran and Sweden are homes

Iman is from Tehran in Iran and he travels home to his family now and then. The new president of Iran has increased optimism and Iman hope that his country is now on the right track after a number of long hard years . We have a whole little Iranian research community at EIT which does its part to feel at home in Sweden . Sweden is a country which he like a lot and is willing to continue to work in. And the meatballs are ok. And salmon. -A good Iranian restaurant called Shiraz in Lund mixes Swedish and Iranian food culture. Free hint of the day from Iman.

Fluent in Swedish of course after 6 years here, I ask. -I'm sorry, no, says Iman a bit embarrassed. Everyone talk english and my girlfriend is good in swedish and do translations for me. I've become "language-lazy" because of that.

Classical Persian music is an interest and Iman excercizes a bit himself on a 6-string tar. His tutor tells him to practice more however. Pleasant audiotones in 2,5 octaves serves as good relaxation inbetween the 60 GHz-sessions in the lab.

From EIT: -Congrats and good luck in the future.

Anders scraps the coils in his RF-receivers

Published: 2015-11-27

Fresh PhD Anders Nejdel.

Streaming video to cell phones is natural to all of us today as a normal phone call was before. It is however not that easy to provide the technology solving it for small mobiles RF-paths. Furthermore, everything that aim to be implemented in consumer products must be cost effective, energy efficient and flexible.

Challenges exist, yes.

-There are lots of challenges, says Anders. To push it all and to not fall into trade-off traps is the hardest. Noise, linearity, power consumption, etc must all be treated in and efficient way. There will also always be new requirements that must be taken into account and flexibility of the systems is necessary in order to let it deal with new scenarios. Moreover, as I have learned now towards the end, it's hard to get everything to work when you have lots of different parts of the receiver on the same chip. The last chip I did also had an analog-to-digital converter which posed certain problems. This was something we first discovered during tests, and a phenomenon that we could not reproduce in the simulator.

Opponent, committee and audience coming in

Theory and practice in good harmony

In his doctoral thesis, Anders Nejdel presents new approaches and ideas for future receiver frontends. As so often in EITs research is not just a question of calculations, theory and circuit-design. Anders solid work also produces actual CMOS circuits and verification of the results with measurements.

In his very educational presentation,  EITs recent doctor explains the methodology where components become circuits followed by fabrication into chips ending up at the lab where evaluation begins, a process which in total takes about half a year. In terms of components, we would prefer not to handle coils since they require space, something that Anders consistently stresses through his research. When asked what is so difficult with coils in microelectronics, Anders tells us:

-Size. Modern circuits optimized for digital applications are always driving transistor size downwards in order to reduce the area and power consumption. This is unfortunately bad for "analog components". Coils do not diminish in size and can take a lot of space. Because the price / area is constantly increasing, this means that price / coil is also constantly increasing.

Pietro Andreani introduces Anders Nejdel and his thesis

Dynamic world

During the presentation we also hear of a straight-on energy comparison in order to understand how much difference there can be between a phone's sent and received signal-power. Power from nuclear power plants is compared with the same thing from a LED lamp. Showing the dynamics of the situation! And in engineering-lingo, what does it mean?

-Around 100 dB, Anders tells us. If you think that a nuclear power plant (size Ringhals) can deliver about 3 GW, and an LED lamp draws about 10W, 100 dB would be the difference between a LED light and the 100 nuclear power plants!

Important researchers for inspiration: Markus Törmänen, Henrik Sjöland, Sven Mattisson, Bo Bernhardsson 

Prestigious invitations

The thesis contains five scientific articles, all based on the results of measurements on 65 nm CMOS circuits and Anders has studied different solutions for flexible receivers. One of the articles shows how to implement a full receiver path from the RF input to digital output.

In the introduction of the disputation, Pietro Andreani mentioned that some of the dissertation articles have been invited to prestigious journals and we are naturally curious about this.

-I have received three invitations, Anders tells us with joy and proudness! Springer Analog Integrated Circuits and Signal Processing. What I am really proud of are the two invitations to the IEEE Journal of Solid-State Circuits (top magazine within integrated circuits). The second article to JSSC was submitted the day before the defense.

Opponent Eric Klumperink and...

Perhaps postdoc…

Asking about "what's next", Anders let us know that it will most likely be a post-doc and "some other stuff", leaving us unaware of details. -And who knows, perhaps industry work in the future, we'll see, Anders says.

...the committee prepare for questioning

Work is not all

There is also a life outside. In that, our fresh PhD is mostly ocuupied with family business. They all live in Kävlinge and his partner Jennie and their daughter Livia get his most attention. Together, they will probably all join in future countryside- and travelexperiences , something Anders like. Travelling has already been a nice part of his research work.



Prefer electronics to biology and chemistry.

-I grew up in Svenljunga, a small village outside Borås, Anders says. After moving to Skåne for high-school, I stayed here. Military service was done in Revinge and followed by technical nanoscience in Lund. It was too much biology and chemistry for me however. I longed for applied sciences and moved to electronics. I was determined to move to industry after my masters but when an opportunity for PhD-studies appeared, I found it exciting. Another four years at LTH! During my research studies I also took part i an exchange program at Marvell, Pavia in Italy for 4 months last year. Lot's of fun and I learned a much.

Congrats from supervisor Henrik Sjöland

EIT congratulates to PhD-exam and wish good luck in coming careers!
