TECHNOLOGY SUMMARY
-Problems to be solved: Conventional piezoelectric measurement device can only measure piezoelectric property of solid material by giving pressure on the solid material. However, it is difficult to measure piezoelectric property of liquid/viscous materials since liquid/viscous materials escape out when pressure is given to the materials. Also, customers have a desire to see and check if the so-claimed electricity generating cosmetics actually generate electricity to have advantageous effects. -The Present Invention relates to a pumping device/cosmetic container that can measure piezoelectric properties for liquid/viscous materials inside the pumping device and show the piezoelectric property of the liquid/viscous materials. The pumping device/cosmetic container includes a nozzle head to dispense liquid/viscous materials outside of a container, a first and a second electrodes to measure charge quantity of piezoelectric material included in the liquid/viscous materials when the liquid/viscous materials are moving, a control circuit for converting the measured charge quantity into voltage signal and amplifying the voltage signal, and an indicator for showing status information of the piezoelectric material. With the pumping device/cosmetic container according to the present invention, customers can check if the electric generating cosmetics actually generate electricity.
