H10N 30/04 Treatments to modify a piezoelectric or electrostrictive property, e.g. polarisation characteristics, vibration characteristics or mode tuning
Introduced: January 2023
Full Title
Full titles differ between systems:
IPC:
Piezoelectric or electrostrictive devices > Manufacture or treatment > Treatments to modify a piezoelectric or electrostrictive property, e.g. polarisation characteristics, vibration characteristics or mode tuning
CPC:
Piezoelectric or electrostrictive devices (integrated devices or assemblies of multiple devices H10N39/00) > Manufacture or treatment > Treatments to modify a piezoelectric or electrostrictive property, e.g. polarisation characteristics, vibration characteristics or mode tuning
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
IPC defines codes here since 2023.
