These (nano) boots were made for walking
The NPRL boasts a stellar cast of Honorary Professors! This month's visitor was ZL Wang from Georgia Tech, pioneer of zinc oxide nanostructures and their applications. ZL has now demonstrated not only the potential of piezoelectric structures to harvest energy from ambient mechanical motion (e.g. walking!) - for self-powered electrical devices - but also piezo-electric logic gates where mechanical strain generates the gate voltage... all since his last visit to Birmingham. We bask in a measure of reflected glory!
