H10N 30/074

by depositing piezoelectric or electrostrictive layers, e.g. aerosol or screen printing

Introduced: January 2023

Full Title

Full titles differ between systems:

IPC:

Piezoelectric or electrostrictive devices > Manufacture or treatment > Forming of piezoelectric or electrostrictive parts or bodies on an electrical element or another base > by depositing piezoelectric or electrostrictive layers, e.g. aerosol or screen printing

CPC:

Piezoelectric or electrostrictive devices (integrated devices or assemblies of multiple devices H10N39/00) > Manufacture or treatment > Forming of piezoelectric or electrostrictive parts or bodies on an electrical element or another base > by depositing piezoelectric or electrostrictive layers, e.g. aerosol or screen printing

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 2023.
