Shwetak Patel and his team, supported by the National Science Foundation, are developing advanced sensing systems to help individuals make informed decisions about energy, water, and health. Initially focusing on energy and water monitoring, they created smart sensors that provide detailed usage data. These sensors use machine learning to identify specific appliances and water fixtures. The technology is now being applied to health monitoring, utilizing smartphone sensors to detect health issues like anemia and jaundice. Patel envisions a future where such sensors are commonplace, aiding in early detection of diseases and environmental monitoring.
