IMB-CNM talks: Nanomechanical sensing based on colorimetric response

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
01/02/2019 11:30 a.m.

Abstract: Nanomechanical sensors have become an emerging and promising technology for sensing and biosensing applications, due to their small size, fast response, high sensitivity and their compatible integration into ‘‘lab-on-a-chip’’ devices. However the multiplexed capability for monitoring several nanomechanical transducers (each one associated with the detection of a specific compound) still present some limitations related mainly with the integration of the read-out methodology when working with an array of transducers (alignment, power,…).
To solve this limitation, we perform a colorimetric detection of nanomechanical bending. We present the development of polymeric nanomechanical sensors (membranes and microcantilevers) with integrated diffraction gratings based on 2D colloidal crystals.
We explore and exploit the white light diffraction to achieve a power-free array of sensors that change their reflective colour depending on the surface stress change (bending) produced on each sensor.

IMB-CNM talks: Efficient generation of proton beam from a 3 TW table-top laser interacting with submicrometric solid targets

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
14/12/2018 11:30 a.m.

Abstract:Thin layer membranes with controllable features and material arrangements are often used as target materials for laser driven particle accelerators. Reduced cost, large scale fabrication of such membranes with high reproducibility, and good stability is central to establish applications of laser driven proton beams.
Beyond introducing the concept and state of art in the field of laser driven particle acceleration, this presentation will focus on the fabrication and characterization of sub-micrometric gold and aluminum membranes embedded in a silicon wafer obtained by applying nano/micro-electro-mechanical-system (N/MEMS) processing and which were then used for laser-driven particle acceleration in the target normal sheath acceleration (TNSA) regime.
Finally, I will discuss results of laser driven proton acceleration experiments carried out on a purpose-made table-top Ti:Sa laser running at 3 TW peak power with a contrast over ASE of 108.

IMB-CNM talks: Self-powered smart patch for cystic fibrosis screening

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
23/11/2018 11:30 a.m.

Abstract:In the presented work, we have developed the first self-powered conductivity sensor focused on screening Cystic Fibrosis (CF). The main core of the device is a paper battery-sensor able to discriminate between different sweat conductivities. The whole device performs the screening of Cystic Fibrosis by measuring the conductivity of the sample, giving a positive result when the CF condition is detected. The validation of the device has been performed following the guidelines of Clinical and Laboratory Standard Institute by testing 40 devices with artificial sweat.
The device has been implemented by integrating a paper battery-sensor in a flexible substrate with a printed electronic circuit, discrete electronic components and electrochromic displays. The design of the electronic circuit has been conceived based on a minimal electronics approach to ultimately make it totally printable.

IMB-CNM talks: Inkjet-printed devices for chemo-/biosensing applications

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
31/10/2018 11:00 a.m.

Abstract: Inkjet printing is a nascent technology that is evolving from text and graphic printing into a major topic of scientific research and R&D, where it can be used as a highly reproducible non-contact patterning technique to deposit liquid functional materials at high speed on either small or large areas of flexible and non-flexile substrates. It is a low cost technique because minimizes the waste products and reduces the process steps. The development of organic materials such as polymers with electrical features has boosted the fabrication of new organic printed electrical devices.
In this framework, the talk is devoted to the development of two novel organic devices for chemo-biosensing applications for a low-cost cost devices using inkjet printing technology. The first sensor is an inkjet-printed Metal-Insulator-Semiconductor (MIS) diode. Its simple fabrication process of these diodes also makes it advantageous for scaling up to roll-to-roll production. Moreover, it has been shown that the MIS diode shows a good selectivity to detect NO2. The second sensor is based on Biological Field-Effect Transistor (BioFET). This device was fabricated and optimized to operate correctly under aqueous media and to detect biomolecules.

Jornada pre-llançament sonda BEPICOLOMBO a Mercuri

El Grup de Dispositius i Sistemes de Potència de l’Institut de Microelectrònica de Barcelona – Centre Nacional de Microelectrònica (IMB-CNM) del Consell Superior d’Investigacions Científiques (CSIC), ha desenvolupat i fabricat un dels components electrònics més crítics de la missió conjunta BepiColombo entre l’Agència Europea de l’Espai (ESA) i de l’Agència Japonesa de l’Espai (JAXA). Aquesta missió té com a objectiu l’estudi aprofundit del planeta Mercuri i té previst situar en òrbita del planeta dues sondes d’exploració que hi arribaran d’aquí 7 anys.
El proper dissabte 20 d’octubre de 2018 a les 1:45 UTC està previst el llançament de la missió BepiColombo des de la base de llançament de Kourou a bord d’un Ariane-V. Per aquest motiu el proper divendres dia 19 d’octubre a partir de les 12h, es realitzaran dues xerrades sobre els reptes tecnològics que ha suposat la missió.
