Characteristics of primal PEG

Further requirements and advancements

dichotomous system

(evaporator and power generator)

simplification

utilizations of devices consuming electricity slightly (electromagnetic valve and diaphragm micro pump)

no external power consuming devices

low vapor pressure impressing frequency (< 1 Hz) dominated by mass transfers

further higher force impressing frequency close to resonant frequency of piezoelectric element

intermittent/sequential operations

simultaneous operations
