Mass sensing using MEMS is crucial for detecting minute changes in mass with high sensitivity, enabling applications in environmental monitoring, medical diagnostics, and chemical detection. However, fluid damping in these environments is relatively high and can lead to reduction of the quality factor and sensitivity of these sensors. In this paper, we present a rotating ring resonator for mass sensing applications and investigate its nonlinear dynamics and bifurcation. The ring is supported by four slender beams and subjected to rotational base excitation. The shift in the nonlinear bifurcation point on the frequency response curve is used for mass sensing, which is significant because the device exhibits multiple nonlinear bifurcation points. The structure is designed and modelled to vibrate in a rotational in-plane mode, to provide lower damping and higher quality factor compared to cantilever-based mass sensors that operate in a translational out-of-plane mode. Moreover, the structure exhibits nonlinear resonance zones within the super harmonic regime, enabling mass detection at a particular fraction of the primary resonance zone. At lower excitation amplitudes, the linear response dominates, and the device also allows mass detection in the linear regime via resonance frequency shifts.

The Floating Solar Photovoltaic System (FSPV) is emerging as a favorable technology to policymakers for economically harvesting renewable energy. The implementation of large-scale photovoltaic (PV) systems is often disrupted due to the unavailability of land. The FSPV systems, where the PV modules are floated in water bodies facilitate optimal utilization of water resources and land assets. The FSPV provides higher power output compared to land-based PV systems of the equal area because of improved energy conversion efficiency at a lower temperature. Another opportunity for the FSPV system is integration with hydropower stations, storage systems, and the electric grid. This paper explores the flood duration curve-based optimal sizing of the FSPV System with the objective of electrification of rural micro-grid. A comparison of energy output and module temperature rise has been made for the FSPV system and its equivalent land-based PV system of equal area. The system generates 18.08 GWh, which is 10.04% more than the land-based PV system. The DC Capacity factor is 17.2%. The Demand Supply Factor (DSF) for a particular day in winter, spring, summer, and monsoon is 37.55%, 41.7%, 45.9%, and 25% respectively. The results indicate that the FSPV system is a sustainable alternative to power renewable energy-based mini micro-grid and provide cost effective electricity to all.
