Piezoelectric film (PVDF) sensor

An ultra-high-sensitivity sensor using a PVDF (Polyvinylidene fluoride) piezoelectric film, a special material that exhibits a piezoelectric effect and can be implemented as a flexible film (resin). 

It is used in various fields, including industrial and medical use, as it is soft and flexible, so there are no restrictions on free shape implementation, and it is expected to expand the scope of use and demand at a rapid pace.

Film Surface Electrode Printing

In order to use piezoelectric film (Piezo Film) as a sensor module, electrode printing is required to obtain sensor signals on the film surface

 ​

 Additional durability is ensured through effective hardening (heat treatment)

 ​

 Anodic (+/-) electrode contact avoidance design ensures stability

 ​

 Ensure safety (durability) of terminal binding
