IMB-CNM talks: Biomedical Micro-and nanoengineering at NMI - Dr. Peter D. Jones

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
19/06/2019 12:00 a.m.

Abstract: The NMI is involved in application-oriented research at the interface between the life sciences and material science. In particular, we apply our core competences in micro and nanoengineering to applications in the life sciences and biomedical engineering. Our expertise includes flexible neural interfaces, microelectrode arrays, microimplants, microsensors and microfluidics. We apply techniques of cleanroom microfabrication, thin film deposition, micro- and nanostructuring, surface engineering, and assembly and packaging. We additionally test devices, surface and coatings for functionality and long-term stability.

We work on flexible electronics as well as on glass, quartz or silicon. Functional structures such as electrical conductors and low impedance electrodes can be structured by optical lithography (1 to 100 µm) as well as electron beam, focused ion beam (FIB) and nanoimprint lithography (>20 nm). We employ biostable electrodes made of titanium nitride, iridium, conductive polymers and carbon nanomaterials (e.g. graphene) with optimal properties for electrophysiology (low noise and/or high charge injection capacity). We produce microelectrode arrays and sensors tailored to specific applications, including implantable devices, ex vivo preparations, and 2D or 3D cell cultures. We additionally specialize in packaging, encapsulation and testing.

L'IMB-CNM projecta el documental “El enigma Agustina” en una jornada dedicada a la dona i la ciència

L’Institut de Microelectrònica de Barcelona (IMB-CNM) organitza el passi de “El enigma Agustina”, el pròxim 14 de juny a les 10.00h, a la Sala d’Actes de la Facultat de Ciències i de Biociències de la UAB. La jornada vol reivindicar el paper de la dona a la ciència.


La sessió, que serà de 10.00h a 14.00h, comptarà amb la participació del guionista i de l’actriu principal. També està prevista una ponència sobre la bretxa de gènere en el camp científic. Serà la primera vegada que el documental es projecta a Catalunya.

“El Enigma Agustina” és un projecte audiovisual de divulgació científica de l’Institut d’Astrofísica d’Andalusia (IAA-CSIC) que aborda la lluita de la dona per accedir a la carrera científica a Espanya i reivindica algunes de les figures femenines de la història de la ciència.

El documental repassa les fites científiques més rellevants del primer terç del segle XX, posant èmfasi en disciplines com la relativitat, la mecànica quàntica i la cosmologia. També permet redescobrir un període de la història recent en què Espanya es va acostar a l'avantguarda científica -l'anomenada edat de plata de la ciència espanyola- fruit del treball de la Junta d'Ampliació d'Estudis (JAE) i de la dedicació de persones com Blas Cabrera, Julio Palacios, Enrique Moles José Castillejo o Felisa Martín Bravo.

Finançada per la Fundació Espanyola per a la Ciència, el documental ha comptat amb la col·laboració de la Societat Espanyola d'Astronomia, la Conselleria de Cultura de la Junta d'Andalusia i l'Institut Andalús de la dona.

IMB-CNM talks: My Ph.D. thesis in a Nutshell - Sofia Otero, Ph.D.

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
31/05/2019 11:30 a.m.

Abstract: An overview of my PhD thesis, entitled ‘Characterisation and Optimisation of Radiation Tolerant Silicon Sensors with Intrinsic Gain’, will be presented. The research work of this PhD thesis was performed in the framework of the RD50 Collaboration, and the CERN Doctoral Student Programme. The objective was to contribute to the development and characterisation of radiation tolerant silicon detectors for high luminosity colliders. The main focus was on silicon sensors for tracking applications within the HL-LHC experiments. Sensors with intrinsic charge multiplication are presently under investigation within RD50. In this thesis, Low Gain Avalanche Detectors (LGADs) and Deep Diffused Avalanche Particle Detectors (DD-APDs) were studied, as they allow to multiply the charge generated by traversing particles. The subsequent increase in the signal produced by the detectors has the potential to improve the signal-to-noise ratio, and with it the efficiency and the time resolution of the detectors. From a solid-state physics point of view, this thesis sheds light on the many phenomena occurring inside silicon devices after heavy irradiation, both with protons and neutrons. From the perspective of detector physics and detector technology, these findings will serve the HL-LHC and other experiments as guidelines for considering the use of devices with intrinsic gain for tracking, calorimetry, or timing applications.

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.

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.
