Piezoelectric Nanogenerators: Polarization‐ and Electrode‐Optimized Polyvinylidene Fluoride Films for Harsh Environmental Piezoelectric Nanogenerator Applications (Small 14/2021)

In article number 2007289, Jong Hoon Jung, and co-workers report a highly stable power source application of piezoelectric nanogenerator in the harsh environmental conditions of cryogenic temperatures, low pressures, large temperature/pressure fluctuations, and strong ultraviolet. The polarization- and electrode-optimized ferroelectric polymer-based piezoelectric nanogenerator can be used in Mars to power light-bulbs by scavenging the mechanical vibrations of dust storms and biomechanical vibrations of astronauts.
