On the optimization and performances of a compact piezoelectric impact MEMS energy harvester

Nico de Rooij, Danick Briand, Pattanaphong Janphuang, Robert Andrew Lockhart

This paper presents the development of a compact energy harvesting configuration to convert low frequency, mechanical oscillations into usable electrical energy using AFM-like MEMS piezoelectric cantilevers coupled to a rotating gear. In this approach, one ...

A task-parameterized probabilistic model with minimal intervention control

Sylvain Calinon

We present a task-parameterized probabilistic model encoding movements in the form of virtual spring-damper systems acting in multiple frames of reference. Each candidate coordinate system observes a set of demonstrations from its own perspective, by extra ...

Thin film bulk acoustic wave resonators tuning from first principles

Alexander Tagantsev, Alexander Kvasov

Being important for the antiresonance frequency tuning of tunable thin Film Bulk Acoustic wave Resonators (FBARs), the non-linear electrostrictive coefficient was for the first time calculated for BaTiO3 and SrTiO3 using ab initio methods. Further, taking ...

Experimental investigation of added mass effects on a hydrofoil under cavitation conditions

Mohamed Farhat, Eduard Egusquiza

The influence of leading edge sheet cavitation and supercavitation on the added mass effects experienced by a 2-D NACA0009 truncated hydrofoil has been experimentally investigated in a hydrodynamic tunnel. A non-intrusive excitation and measuring system ba ...

Minimalistic Models of an Energy Efficient Vertical Hopping Robot

The use of free vibration in elastic structure can lead to energy efficient robot locomotion, since it significantly reduces the energy expenditure if properly designed and controlled. However, it is not well understood how to harness the dynamics of free ...

Engineered Absorption Enhancement and Induced Transparency in Coupled Molecular and Plasmonic Resonator Systems

Hatice Altug, Shyamsunder Erramilli

Coupled plasmonic resonators have become the subject of significant research interest in recent years as they provide a route to dramatically enhanced light-matter interactions. Often, the design of these coupled mode systems draws intuition and inspiratio ...

Dynamics Modeling and Control Architecture for Efficient, Manoeuvrable and Robust Monoped Hopping over Rough Terrain

Auke Ijspeert, Salman Faraji, Soha Pouya, Rico Möckel

Leg dynamics and control have been widely studied using mass-spring systems such as the Spring Loaded Inverted Pendulum (SLIP) model [1]. The SLIP model is commonly accepted as the simplest model that resembles leg dynamics. While simplicity facilitates th ...

An Artificial Muscle Ring Oscillator

Dielectric elastomer artificialmuscles have great potential for the creation of novel pumps, motors, and circuitry. Control of these devices requires an oscillator, either as a driver or clock circuit, which is typically provided as part of bulky, rigid, a ...

Analysis of the dynamic response of pump-turbine runners- Part I: Experiment

François Avellan, Mohamed Farhat, Xiaopeng Huang, Eduard Egusquiza

When in operation, pump-turbine runners have to withstand large pressure pulsations generated by the rotor-stator interaction. The analysis of the dynamic behavior of these structures is necessary to avoid damage. For this analysis a realistic model of the ...

Constrained spectrum control using MPC

Colin Neil Jones, Jean-Hubert Hours

Well-known model predictive control (MPC) theory for constrained linear time-invariant (LTI) systems is extended to accommodate hard constraints and cost penalizations on the spectra of the system’s output trajectories. Thus the proposed method facilitates ...
