Abstract Carbon dioxide (CO2) has been linked to many deleterious health effects, and it has also been used as a proxy for building occupancy measurements. These applications have created a need for low-cost and low-power CO2 sensors that can be seam

This work considers the response of a globally coupled array of oscillators, each with cubic nonlinear stiffness, in the presence of global reactive and dissipative coupling. Based on the continuum formulation for this system first presented in C. Bo
