We provide ultrasound transducers and hydrophone made with high performance piezoelectric P(VDF-TrFE) copolymer film with thickness of 9 um, 12 um, 20 um, 25 um, and 40 um) with typical sizes from 3 mm to 8 mm. They have 100 nm thick gold electrode and they are in stock. They will be shipped within 24 hours after receiving payment.
Impedance spectrum will be provided to show their dielectric constant, resonance frequency, coupling factor.
Other thickness and size can be customized with reasonable lead time.
