UR-SolarCap An Open Source Intelligent Auto-Wakeup Solar Energy Harvesting System for Supercapacitor-Based Energy Buffering

UR-SolarCap: An Open Source Intelligent Auto-Wakeup Solar Energy Harvesting System   for Supercapacitor-Based Energy Buffering  Abstract: Energy harvesting systems that couple solar panels with supercapacitor buffers offer an attractive option for powering computational systems deployed in field settings, where power infrastructure is inaccessible. Supercapacitors offer a particularly compelling advantage over electrochemical batteries for such settings because […]


Smart phone-based peak expiratory flow meter

Smart phone-based peak expiratory flow meter Abstract: The design and performance of a smart-phone-based device, called AudioFlow, that measures and records peak expiratory flow (PEF) is presented. PEF is a measure used by asthma sufferers to monitor their asthma conditions. The device is comprised of a custom 3D printed airtube and a minimal number of electronic […]
