The JLB was founded in 2012 at th Institute of Biotechnology of Technische Universität Berlin. It is headed by Profs. Mario Birkholz and Peter Neubauer. Currently, topics such as biosensors with microring resonators, electrically induced lysis, cell separation, clean room fabrication of lab-on-chip systems and design of privacy-securing implants are investigated. Every summer semester an introductory course to Bioelectronics is offered (in German language). tfr

The #smartphone 📱 is next to you and your #attention is waning!
The mere presence of a smartphone negatively affects #cognitive performance 🧠, as a study by Skowronek et al. shows:
https://www.nature.com/articles/s41598-023-36256-4
The study participants, aged between 20 and 34, underwent attention and concentration tests in the presence and absence of a smartphone. The results showed that the presence of a smartphone strains cognitive resources and reduces performance.
The mere presence of a smartphone reduces basal attentional performance - Scientific Reports

The smartphone has become an indispensable part of everyday life. It enables endless possibilities and offers persistent access to a multiplicity of entertainment, information, and social contacts. The development towards a greater use and a persistent presence of the smartphone does not only lead to advantages, but also raises potential for negative consequences and a negative influence on attention. In this research, the hypothesis of the mere smartphone presence leading to cognitive costs and a lower attention is being tested. The smartphone may use limited cognitive resources and consequently lead to a lower cognitive performance. To investigate this hypothesis, participants aged 20–34 perform a concentration and attention test in the presence and absence of a smartphone. The results of the conducted experiment imply that the mere presence of a smartphone results in lower cognitive performance, which supports the hypothesis of the smartphone presence using limited cognitive resources. The study as well as the subsequent results and the resulting practical implications are presented and discussed in this paper.

When discussing the #sustainability of #smartphone use, the elephant in the room often goes unmentioned: the enormous #profits that the big #tech companies are making with their monopolistic position.
While education and social budgets continue to shrink, the companies' revenues continue to grow. The new publication

proposes to initiate an #expropriation of the profits of tech companies in accordance with Art. 17 of the EU Constitution.

If you want to use your #smartphone sustainably, you should track the #battery consumption.
With the two dominant operating systems, this is only partially possible.
They show which #apps consume how much % → Image below from the new work

Significant savings are possible if #GPS and #WLAN are only switched on when needed or - even better - an OS like #Sailfish is used. More info here

the researchers not only examine the #energy consumption of #smartphone use.
Rather, they include all 17 UN Sustainable Development Goals in the analysis.
For 10 of the 17 goals, conflicts are identified between smartphone use and the pursuit of #sustainability.
The problems are mainly due to the existing oligopoly for mobile #operating systems and (un) #socialmedia.

Almost 7 billion smartphones are in use around the world.
And like many other systems in the #ICT sector, they are contributing more and more to #energy consumption and #CO2emissions.
However, the energy consumption of smartphones is mainly due to mobile #data transmission and #datastorage in data centers.
This is shown by the recently published paper “Sustainable use of a smartphone ...”

“#Sustainable use of a #smartphone ...”

Under this title, Martin #Kögler, Katharina #Paulick, Jürgen #Scheffran and Mario #Birkholz have published a paper in the journal “Sustainable Development”, which was released today:

https://www.researchgate.net/profile/Martin_Koegler/publication/380177615_Sustainable_use_of_a_smartphone_and_regulatory_needs/links/663130d908aa54017acf97e3/Sustainable-use-of-a-smartphone-and-regulatory-needs.pdf

Three of the authors held a workshop at #Bits&Bäume 2022 entitled “How much energy does my cell phone use to monitor me?”
With the participation of climate researcher J. Scheffran, the question has now been examined even more comprehensively.

The #Fraunhofer #IPMS in Dresden has developed a new type of sensor layer for chip-based #pH measurements. The metal oxide-based sensor layer is integrated in a 5x5 mm^2 compact #ion-sensitive #field-effect transistor (#ISFET). In combination with a conventional reference electrode, precise measurements between pH1 and pH13 with a drift of < 20µV/h can be performed. However, the integrated reference electrode still needs to be developed. 🙈

Innovation in der Sensorik: Neuentwicklung einer pH-Sensorschicht erfolgreich in ISFET integriert - Fraunhofer IPMS

Das Fraunhofer-Institut für Photonische Mikrosysteme IPMS verkündet einen bedeutenden Fortschritt in der chemischen und biochemischen Analytik. Das Team um Geschäftsfeldleiter für Chemische Sensorik, Dr. Olaf R. Hild, hat erfolgreich eine wegweisende Sensorschicht für chipbasierte pH-Messung entwickelt und diese erfolgreich in einen Ionensensitiven Feldeffekttransistor (ISFET) integriert.

#GreenSoftware Engineering aims to promote #sustainability on the #Internet, ideas for implementation are explained in this article: https://spectrum.ieee.org/green-software
#Software with unclean codes and wrong-sized images have a negative impact on energy consumption and higher #CO2emissions than green software that is efficient and can create higher quality systems. That's why the #GreenWebFoundation is working towards the ambitious goal of making the internet fossil-free by 2030.

The #IMEC recently presented an extremely small wireless power supply unit that works with ultrasound. It makes it possible to charge neural and other #implants with low power consumption. Since conventional power supply methods pose a risk to patients, the IMEC developed an #ultrasound technology whose radiation can penetrate the skull. The new technology can charge implants wirelessly.
