IMB-CNM talks: Implantable and wearable technologies at the center for biomolecular nanotechnologies - Prof. Massimo De Vittorio

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
17/05/2019 11:30 a.m.

Abstract: The combination of genetics, photonics, electronics and micromechanics is enabling completely new micro- and nano-technological approaches for compact and effective tools for diagnostics and therapeutics, which can be disposable, wearable, implantable or tattooable. These new approaches are opening the way to closed loop theranostics, i.e. devices integrating diagnostic capabilities and therapeutic response. In this context, the center for biomolecular nanotecnologies (CBN) is exploiting new technological approaches to produce innovative in-vivo implantable/wearable devices and in-vitro assays. Recent results on implantable probes and optrodes for optogenetics, on piezoelectric microelectromechanical systems (MEMS) for wearable sensing and for energy harvesting from the human body will be presented and discussed.

IMB-CNM talks: Tactile intelligence enabled by Flexible Iontronic Sensing (FITS) - Prof. Tingrui Pan

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
23/04/2019 11:30 a.m.

Abstract: Artificial Intelligence (AI) has become an extremely popular subject to explore in both industries and academia recently, in which a variety of machine vision and voice recognition technologies have been established to enable such human-machine interfaces. As the next phase of artificial intelligence, tactile intelligence by offering a completely new means to facilitate in the human-everything communications, where high-sensitivity, noise proof sensing mechanisms with long-term functionalities play critical roles in a real-world implementation, while the existing mechanical sensing technologies (i.e., resistive, capacitive, or piezoelectric) have yet offered a satisfactory solution to address them all.
Here, we successfully introduced various flexible supercapacitive sensing modalities to both natural and artificial materials for wearable pressure and force sensing using an elastic ionic-electronic interface. Notably, an electrospun ionic fabric utilizing nanofibrous structures offers an extraordinarily high pressure-to-capacitance sensitivity (114 nF∙kPa-1), which is at least 1,000 times higher than any existing capacitive sensors and one order of magnitude higher than the previously reported ionic devices, with a pressure resolution of 2.4 Pa, achieving high levels of noise immunity and signal stability for wearable applications. In addition, its fabrication process is fully compatible with existing industrial manufacturing and can lead to cost-effective production for its utility in emerging wearable uses in a foreseeable future.

IMB-CNM talks: 4-Quadrant Si-Photodiodes for Attitude Control of OneWeb Satellites Constellation - J.M. Moreno and M.Rodríguez

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
09/04/2019 12:00 a.m.

Abstract: OneWeb Satellites consists of the design, development, construction and launch of a megaconstellation of 900 satellites, with the aim of providing global high-speed Internet connection. OneWeb Satellites is a company founded by Airbus and OneWeb, for the design and production of this constellation. The first six satellites of the OneWeb megaconstellation flew successfully from the Guiana Space Center on February 27th and are now orbiting around Earth at 1,000 km.
Solar MEMS Technologies participates in this Project as official supplier of the sun sensors for the satellites of the constellation. These miniaturized units are mentioned to detect the Sun position while in orbit to let the satellite gets correctly oriented during different scenarios. Solar MEMS has designed and developed a customized sun sensor fulfilling OneWeb Satellites requirements, with an initial order of more than 1800 units to be integrated in the satellites of the constellation.
For this purpose, the sun sensors supplied by SolarMEMS to OneWeb Satellites are equipped with silicon photodiodes designed and fabricated by D+T Microelectrónica A.I.E. at IMB-CNM (CSIC). Today more than 4000 Si-photodiodes have been manufactured by D+T, covering more than 36 wafers, and has completed a test campaign including radiation tests per wafer, thermal tests, life tests and mechanical vibrations. Additionally, lot of data has been collected by Solar MEMS to do a deep data analysis and scientific comparison, allowing a new way for industrial and technical analysis never done before in Space Industry.

Scientific Meeting of BNC-b Students

The "Scientific Meeting of BNC-b Students" organized by PhD fellows and open to undergraduate, master students and PhD researchers, comes back in 2019! The meeting is aimed to present the work performed by PhD students of the whole Barcelona Nanotechnology Cluster – Bellaterra (ICMAB, ICN2, IMB-CNM, UAB, ALBA), promoting collaborations between them in an academic and scientific environment. The meeting will be held at ICMAB and ICN2 on 6-7 June 2019. Abstracts and registration deadline: 26 April 2019. Will you miss it?.


Growing originally from the “1st Meeting of ICMAB Students” in 2011, the “Scientific Meeting of BNC-b Students" was established successfully as an organized networking and dissemination platform in its first three editions in the years 2015, 2016 and 2017. We are pleased to announce the comeback of the conference in 2019.

The "4th Scientific Meeting of BNC-b Students" is aimed to present the work performed by PhD students of the whole Barcelona Nanotechnology Cluster – Bellaterra (ICMAB, ICN2, IMB-CNM, UAB, ALBA), promoting collaborations between them in an academic and scientific environment.

The event incorporates the entire framework of the UAB Research Park, as well as other universities as UB or UPC. Moreover, it is also opened to undergraduates, master students and the scientific community at large.

The meeting structure of the 4th edition will include the usual oral presentations and posters. Furthermore, we will invite high profile speakers to share with us their experience working in companies, as magazine editors or in the world of divulgation. They will also talk about the skills acquired during the PhD that can be useful outside the academic world, so this event represents a good chance to meet people who have already followed this path and who can give you good advice.

Here you will have the opportunity to meet other PhD students, and share your experience and research from different nanoscience areas.


The program is organized into different topics, all related to the "nano universe", allowing you to focus on your specialty as well as expand your knowledge in other areas. Attendees will be able to learn from over 50 different researches, including oral sessions, poster presentations, invited speakers and a round table, and also have fun with some monologues related with the scientific world.


The speakers will have 10-15 minutes for the presentation and 5 minutes to answer possible questions. The talks will be in English. Don't worry if you don't have a good level, the best place to practice is this friendly environment.

The best oral and poster presentations at the conference will be prized. They will be judged during the sessions and prizes & certificates will be delivered to the winners during the conclusion of the meeting.


Registration is open until April 26, 2019 on this link.


The meeting is organized by PhD Students of the BNC-b with the support of all the centers forming part of the nanocluster:

IMB-CNM talks: Suspended Micro-nanogenerators for cell stimulation - Carolina Vargas Esteve

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
08/02/2019 11:30 a.m.

Abstract: Electrical stimulation has been used in many therapeutic applications to modulate cellular activity, restore biological lost functions or even improve the performance of certain tissues. Micro/nanogenerators play a key role as self-powered devices to replace the bulkiness or lack in specificity of nowadays electrical stimulation. Their high spatial resolution and acute cell specificity allow them to stimulate single cells in its own liquid media.

This work explored two technological branches based on photovoltaic and on magnetoelastic (piezoelectric/ magnetostrictive) devices to generate energy at the micro/nanoscale. We will explain their fabrication, characterization and biological evaluation to demonstrate the feasibility of them as functional tools for bioapplications.
