Energysensing

Energysensing is the detection, measurement, and interpretation of energy flows, storage, and status in physical, biological, and engineered systems. It encompasses electrical power monitoring, optical energy detection, environmental energy resource assessment, and physiological or cellular energy status. The aim is to quantify variables such as energy rate, energy content, or metabolic energy state to inform control, design, and analysis.

Energysensing in electrical systems involves capturing voltage and current and computing power, energy use, and demand. Tools include current sensors, voltage dividers, power meters, and smart meters deployed in homes and grids. Data enable load forecasting, efficiency programs, and grid stability. Calibration, linearity, and noise reduction are important considerations.

Optical energy sensing and environmental energy assessment cover photodetectors that convert photon energy to an electrical signal, spectrometers that measure spectral energy distributions, and radiometers that quantify total optical energy. In energy harvesting and building optimization, sensing ambient solar irradiance and wind availability informs control and storage strategies.

Biological and physiological energysensing addresses cellular energy status through sensing molecules such as ATP and AMP and signaling pathways like AMP-activated protein kinase. In physiology, metabolic rate and energy expenditure are estimated via calorimetry and wearable sensors, guiding health assessment and performance optimization.

Applications of energysensing span smart grids, industrial automation, environmental monitoring, and biomedical research. Methods range from calorimetry and electrical sensing to optical detection and multi-sensor data fusion. Key challenges include measurement accuracy, sensor calibration, data privacy, and integrating disparate energy signals for real-time decision making.
