Hoboken, NJ, November 18, 2010 --(PR.com
)-- Dr. Yong Shi of Stevens Institute of Technology delivered a keynote presentation on Tuesday, November 16 regarding his research of Piezoelectric Energy Harvesters at the Energy Harvesting and Storage USA 2010 Conference in Cambridge, Massachusetts. The talk, “Mechanical Energy Scavenging Using Piezoelectric Fibers,” discussed the development of a new kind of high voltage and power output nanogenerator based on patented piezoelectric (PZT) nanofiber technology. The nanogenerator was fabricated in the Active Nanomaterials and Devices Laboratory and Micro Device Laboratory at Stevens, The Innovation University™. Dr. Shi’s National Science Foundation (NSF)-funded research was previously featured in Nanoletters in a paper titled “1.6 V Nanogenerator for Mechanical Energy Harvesting Using PZT Nanofibers.”
A brief overview of the paper has been published online at: http://buzz.stevens.edu/index.php/nanoletters-yong-shi-nanogenerator
PZT nanofibers convert mechanical energy from movement into electricity, eliminating the need for batteries. For example, the nanogenerators can provide uninterrupted power to pacemakers or nanodevices carried in the bloodstream, relying only on blood pressure and body movement to provide a charge. The technology can be used in a variety of applications, including wireless sensors, personal electronics, implantable bio-sensors, and bio-actuators. The low-cost, flexible nanogenerator can also be packaged in bio-compatible polymer and embedded in clothing in order to harvest the motion energy of human body to charge battery for devices such as mp3 players and cell phones. “We are excited about the concept reported here in designing the PZT nanofiber-based nanogenerator and its immediate technological applicability in a broad range of disciplines,” Dr. Shi says.
