Special Session 13

Progresses on methodologies and devices for Energy Harvesting in autonomous or quasi-autonomous Sensors and Transducers

 

Description

Recently, there has been an increasing demand for self-powered sensor nodes, smart sensing devices and autonomous measurement systems based on novel transducers for energy scavenging.

It must be observed that energy scavengers for sensing elements and transducers arouse interests in the international community with particular emphasis in the area of measurements and metrology where the interest to recovery energy from the environment and to supply or to sustain measurement architectures is highly felt in macro scale but also in integrated scale (MEMS, Micro-Electro-Mechanical-Systems) and nano scale (NEMS, Nano-Electro-Mechanical-Systems).

It is worth noting that several ways to optimize the amount of harvested energy coming from the environment (i.e. kinetic vibrations), have been explored in literature, as regards the conversion, extraction mechanisms and the exploitation of nonlinearity in order to improve the performance of the device which is able to supply or to sustain the specific sensor or transducer.

The session will be devoted to linear and nonlinear transduction methodologies for efficient collection of energy from environmental sources, to methodologies for characterization and efficiency evaluation, to applications and development of battery-less sensors and transducers, to design and fabrication of novel transducers also at MEMS and NEMS scale, to autonomous and self-sustained low-power devices.

Submissions are welcome but not limited to the following topics:

  • Self-powered and autonomous sensors
  • Transducers for energy scavenging
  • Novel methodologies of measurement based on nonlinear behaviours
  • Linear and Nonlinear mechanisms and techniques
  • Emerging technologies and methods for energy harvesting
  • Power management and interfaces
  • Models and simulations in energy harvesters for sensor and transducers

Multiple response of nonlinear energy harvesting in the presence of noisy and periodic components

 

Abstract

An autonomous system of energy supplier to low power devices or wireless sensors is one of the most important motivations for energy harvesting based on ambient mechanical vibrations. A frequency broadband nonlinear resonator with multiple well potentials and/or impacts with the aim of increasing the range of operativity of the transducer. The excitations are modeled by kinematic forcing possessing periodic and stochastic components [1,2], motivated by realistic ambient conditions. We show how the noise component of the excitation influences the stability of the solution.

Bio

Grzegorz Litak was born in 1963 in Lublin, Poland. He completed his M.Sc. degree in physics at Maria Curie Skodowska University (UMCS) in Lublin, Poland in 1988. Later, working on the effect of disorder on correlated and exotic superconductors, he received his Ph.D (1994) and D.Sc (2002) degrees from the same University. Later his theoretical studies included properties of multiorbital superconductors. After defending his Ph.D thesis he moved to Technical University in Lublin where he is presently working as a full professor and a head of department of Automation. From that time (1994) he also started his research on mechanical engineering, production engineering, and nonlinear dynamics. He focused on bifurcation theory, chaotic dynamics and nonlinear time series analysis. Recently, he was involved in research on mechanical energy harvesting, especially by modelling and simulating of energy harvesters for sensor and transducers, where he applied system nonlinearities to realize advantages of frequency broadband effects. From 2016 prof. Litak works also at AGH University of Science and Technology at the Department of Process Control. Prof. G. Litak published over 250 papers including about 160 in international journals. His impact of publications is measured by the h-index in the SOPUS base is h=24 while in the Web of Science h=22. He is actively collaborating with many researchers from other Institutes, while being a visiting scientist at UMCS in Lublin, Bristol University, Swansea University, ICTP in Trieste, University of Trieste, Max Planck Institute in Dresden, Technical University of Vienna, Technical University of Chemnitz, Oak Ridge National Laboratory, Cleveland State University, Indiana University-Purdue University Indianapolis, Rey Juan Carlos Universidad in Madrid, University of Marche in Ancona, and University of Aberdeen, Autonomus University of Barcelona, Polytechnic University of Catalonia, Unversity of Tartu, and INSA Lyon. Presently, he is a member of the Polish Physical Society, the Polish Society of Theoretical and Applied Mechanics, and also the EUROMECH society. He was an associate editor of the Journal of Applied Sciences (2008-2011) Journal of Chaos (2014-2015), presently, an associate editor of the Open Applied Physics and the Advances in Science and Technology Research Journal. He proposed 4 doctors in the field of mechanics and machine design.
