More autonomy for miniature connected objects

These promising developments are detailed in an article co-authored by a researcher at the university.

Over the last decade, connected objects have become an important part of our daily lives for a variety of applications (leisure, surveillance, measuring vital health parameters, etc.) - this is the field of the Internet of Things (IoT). As soon as these objects are mobile (watches, drones, etc.), their autonomy is generally rapidly limited. Managing to supply them with sufficient energy is now a major challenge for research. This is also the case for even smaller communicating objects, which are about the size of a grain of rice. These miniature objects could be used for the local delivery of drugs to the human body, the monitoring of polluted areas that are inaccessible or the medical surveillance of patients.

In an article in the newspaper Energy & Environmental Sciencea teacher-researcher at the university (see box) and two colleagues from Nantes have produced a detailed review of the challenges of energy autonomy for the Internet of Miniature Objects. To ensure this autonomy, two complementary electrochemical energy storage devices are the focus of intense research by the various laboratories involved. The first is responsible for supplying continuous energy to the object. It is based on miniaturised lithium ion batteries.

The second, which is the focus of this article, is manufactured to respond to intense current peaks. These are very fast, millimetre-sized supercapacitors: micro-supercapacitors.sators. It's difficult to store a large amount of energy in such a small space. Increasing it significantly is the focus of current research. But nature offers a number of ways of improving performance. For example, to maximise the surface area for exchanging oxygen with the blood, our lungs contain hundreds of millions of alveoli in a 3D structure reminiscent of a tree. Similarly, in micro-supercapacitors, the use of the third dimension makes it possible to increase the surface area of interaction between their two main components (the electrode materials and the electrolyte ions) without altering the size of the object. By mimicking these biological structures, the performance of 3D micro-supercapacitors improves significantly, enabling them to store a quantity of energy never achieved by their 2D predecessors.

Christophe Lethien is a lecturer at the University of Lille, at the faculty of science and technologyand researcher at theInstitute of Electronics, Microelectronics and Nanotechnologies (IEMN). The article is published in collaboration with Jean Le Bideau and Thierry Brousse, teachers atUniversity of Nantes and researchers at theNantes Materials Institute (IMN). The three researchers are members of the electrochemical energy storage network (RS2E).

Abstract:

For realistic 3-D feedback flow control applications, wall measurements tend to be more practical than velocity field measurements. The measurement of mean and fluctuating wall shear-stress and pressure in a boundary layer finds applications both in industry and the scientific community. Time-resolved data can provide physical insight into complex flow phenomena, including turbulent viscous drag, transition to turbulence, and flow separation. The ability for the direct measurement of wall shear-stress as a vector field offers advantages over indirect measurements for pressure sensing for separation detection and flow state estimation for 3D flow control applications. Specifically, when the control objective is often skin-friction or pressure drag reduction, a direct measurement of these quantities may be preferable. This talk presents the design, fabrication and calibration developments of a direct MEMS-based capacitive shear stress sensing system to address both fundamental physics measurements and flow control applications.

Abstract:

To understand and mitigate the impact of noise sources on an aircraft, aeroacoustic researchers are in need of a high performance, low cost microphones to address the increasing noise restrictions on commercial aircraft. Existing commercial sensors, even with their relatively high cost, in some cases constrain the quality and type of measurement that may be achieved. This talk presents the design, fabrication and calibration developments of the first truly flush-mount piezoelectric microelectromechanical (MEMS) dynamic pressure sensor with associated packaging for aircraft fuselage arrays. Through-silicon-vias (TSVs) are incorporated into the fabrication of the sensor to eliminate front-side wire bonds and enable an overall flush surface for the packaged sensor that minimizes flow disturbance. The developed packaging method for the sensor demonstrates an overall flushness to within 10 μm, showing substantial improvement from any previously reported efforts.

Thèse : Développement de micro-capteurs de frottement pariétal et de pression pour les mesures en écoulements turbulents et le contrôle de décollement

Summary:

Le contrôle des écoulements vise à modifier le comportement naturel d’un écoulement fluidique. Dans le domaine des transports, contrôler les phénomènes fluidiques tels que le décollement peut permettre d’économiser du carburant, d’améliorer les performances des véhicules ou encore d’assurer davantage la sécurité des passagers. Dans ce contexte, des capteurs avec de fines résolutions temporelle et spatiale sont requis afin de connaître l’écoulement à contrôler et adapter en temps réel le contrôle.  Dans ce travail, l’objectif a été de développer des micro-capteurs de frottement et de pression pour les mesures en écoulements turbulents et le contrôle de décollement.
Tout d’abord un micro-capteur calorimétrique a été conçu et réalisé par des techniques de microfabrication pour mesurer simultanément le frottement pariétal et la direction de l’écoulement. Le micro-capteur a ensuite été intégré en paroi d’une soufflerie afin de réaliser son étalonnage statique et dynamique et d’étudier sa sensibilité à la direction de l’écoulement. Troisièmement, le micro-capteur calorimétrique a été utilisé pour caractériser des écoulements décollés.  Plusieurs micro-capteurs avec électronique miniaturisée ont été intégrés avec succès dans une maquette de volet et des essais de contrôle actif ont été réalisés. Enfin, la quatrième partie concerne le développement d’un micro-capteur de pression et d’un micro-capteur multi-paramètres réunissant les deux technologies.
L’ensemble de ces micro-capteurs a caractérisé avec succès et montre des résultats prometteurs pour caractériser les écoulements turbulents et permettre la mise en place de contrôle d’écoulement en boucle fermée.

Development of wall shear stress and pressure micro-sensors for turbulent flows measurements and flow control

 

Summary :

Flow control aims at artificially changing the natural behaviour of a flow. In transport industries, controlling fluidic phenomena such as boundary layer separation allowssaving fuel and power, improving vehicles performances or insuring passenger’s safety. In this context, sensors with accurate spatial and temporal resolution are required. Such devices enable to estimate the flow to control and allow real-time adaptation of the control. In this work, the objective is to develop wall shear stress and pressure micro-sensors for turbulent flows measurements and flow separation control.
Firstly, a calorimetric micro-sensor was designed and realized using micromachining techniques for measuring simultaneously the wall shear stress amplitude and the flow direction. Secondly, the micro-sensor was flush-mounted at the wall of a wind tunnel for static and dynamic calibrations. Thirdly, it was used to characterize separated flows. Several configurations were studied: separation on airfoil profile, separation and reattachment downstream a 2D square rib and the separation on a flap model. Several micro-sensors with embedded electronics were successfully integrated on a flap model and active flow control experiments were performed. Finally, the fourth part of the document concerns the development of a pressure micro-sensor and the development of a multi-parameter micro-sensor combining both technologies.
All these micro-sensors have been successfully realized and characterized and demonstrate promising results for measuring turbulent flows and implementing closed loop reactive flow control.

Abstract:

In this talk, a review of recent advancements on simultaneous information and energy transmission (SIET) is presented. More specifically, SIET refers to communication systems in which a set of transmitters aim to simultaneously carry on two tasks: information transmission to a set of information receivers (IRs); and energy transmission to a set of energy harvesters (EHs). The performance of SIET is often measured by the information and energy transmission rates that can be simultaneously achieved under certain reliability constraints, e.g., decoding error probability (DEP) and energy shortage probability (ESP). The fundamental limits of SIET consist of the largest set of information and energy rates  that can be simultaneously achieved with bounded DEP and ESP. In general, these fundamental limits are often referred to as the information-energy capacity region. The talk focuses on the study of the information-energy capacity region of three channel models: point-to-point channels, multiple access channels and interference channels.
