“…This is in turn important for two reasons mainly: Fabrication uncertainties or tolerances, which will result in non-perfectly identical devices; and dynamic range, since from the moment that events start to happen to a particular resonator in the system, symmetry will be broken. Many interesting systems have been presented even with this limitation being present: Arrays of many resonators with small (Stassi et al, 2017;Stassi et al, 2019) or large coupling (Marquez et al, 2017); mass sensors (Thiruvenkatanathan et al, 2010a;Wang et al, 2018), electrometers (Thiruvenkatanathan et al, 2010b), accelerometers (Pandit et al, 2019;Wang et al, 2020;Zhang et al, 2020;Zhang et al, 2021), etc. In order to bypass the limitation, two approaches have been suggested. One option is to stop looking into mode localization, but still looking at the eigenmodes rather than the eigenvalues as a sensing parameter.…”
