Time-modulated inerters as building blocks for nonreciprocal mechanical devices
Paolo Celli, Antonio Palermo
In this work, we discuss the realization of mechanical devices with non-reciprocal attributes enabled by inertia-amplifying, time-modulated mechanisms. Our fundamental building-blo…
Experimental Evidence of Amplitude-Dependent Surface Wave Dispersion via Nonlinear Contact Resonances
Setare Hajarolasvadi, Paolo Celli, Brian L. Kim +2
In this letter, we provide an experimental demonstration of amplitude-dependent dispersion tuning of surface acoustic waves interacting with nonlinear resonators. Leveraging the si…
Modelling planar kirigami metamaterials as generalized elastic continua
Yue Zheng, Imtiar Niloy, Ian Tobasco +2
Kirigami metamaterials dramatically change their shape through a coordinated motion of nearly rigid panels and flexible slits. Here, we study a model system for mechanism-based pla…
Capacitive temperature sensing via displacement amplification
Semih Taniker, Vincenzo Costanza, Paolo Celli +1
We propose the realization of capacitive temperature sensors based on the concept of displacement amplification. Our design features two high coefficient of thermal expansion (CTE)…
The detection matrix as a model-agnostic tool to estimate the number of degrees of freedom in mechanical systems and engineering structures
Paolo Celli, Maurizio Porfiri
Estimating the number of degrees of freedom of a mechanical system or an engineering structure from the time-series of a small set of sensors is a basic problem in diagnostics, whi…
Sparse metapiles for shear wave attenuation in half-spaces
Paolo Celli, Ilaria Nunzi, Andrea Calabrese +2
We show that shear waves traveling towards the surface of a half-space medium can be attenuated via buried one-dimensional arrays of resonators -- here called metapiles -- arranged…
