This metal, which is metal from glass microcapsules and liquid metal. This metal, more than 20% lighter than bulk material, also shows a unique which is more than 20% lighter than bulk material, also characteristic: high-frequency oscillation is greatly attenuated when shows a unique characteristic: high-frequency oscillation is propagated in its medium. greatly attenuated when propagated in its medium.P-p printer systemP-p printer system Present piezoelectric polymer dual head printer system Presentpiezoelectricpolymerdualheadprintersystem(P-pdualheadprintersystem)enableustoprintthefinePVDFfilmsona(P-p dual head printer system) enable us to print the fine PVDF films on a substrate.
