Eliminating lead-exposure in nebulization therapy by lead-free piezoelectric [PDF]
Nature CommunicationsPresent main-stream medical ultrasonic nebulizers contain Pb(Zr,Ti)O3-based piezoceramics, which could expose the patients to toxic lead when the acidic liquid medicine, compounded with ultrasonic vibration, corrodes the piezoceramics. Enormous amount of
