Transient response of thermocapillary pumping of a droplet in a micro heat engine
A. Odukoya,Greg F. Naterer +1 more
TL;DR: In this paper, a new analytical model is developed to predict the transient velocity and voltage generated due to thermocapillary pumping in a micro heat engine (MHE), which uses lead zirconate titanate (PZT) as a substrate for the MHE.
