Flexible Sensors and Energy Harvesters
Sponsored by: NSF, NIH R01 and The Arthur. L. Irving Institute for Energy and Society.
Cardiovascular disease is the #1 killer in the US and worldwide. Consequently, there is an upsurge in the various novel devices to diagnose, monitor, and treat cardiovascular disease. With the emergence of piezoelectric nanogenerator based sensor and energy harvester, we have developed three projects relevant to nanomaterials based pressure sensors and power harvesters.
