Summary
Researchers at Vanderbilt University have developed a new method of producing microscale and nanoscale ferroelectric fluids. These particles are useful in a variety of piezoelectric, pyroelectric, and electrooptic devices such as thin-film capacitors, electronic transducers, actuators, high-k dielectrics, pyroelectric sensors, and optical memories.

Technology Description
This innovative technology provides a method of producing ferroelectric nanofluids in any microscale or nanoscale size. The method of producing these particles uses quantum dots mixed with antimony salts to yield agglomerates of particles that exhibit extreme susceptibility to electric fields. These agglomerates can be reduced in size through various methods in order to obtain smaller agglomerates of ferroelectric particles. Mobility within an applied field is size-dependent, with smaller sizes demonstrating higher mobilities, allowing for manipulation of the nanofluid with minimal electric field (including static electricity from fingertips).
