Enabling High-Speed Modulation And Wide Bandwidth With LNOI POI
Piezo on Insulation (POI) refers to a technology where piezoelectric materials are integrated onto an insulating substrate. This allows for the utilization of the piezoelectric effect while providing electrical isolation. The POI technology enables the development of various devices and systems that harness the unique properties of piezoelectric materials for sensing, actuation, and energy harvesting applications.
POI (Piezo on Insulation) technology finds various applications in different fields due to its ability to combine the advantages of piezoelectric materials with electrical isolation. Such as sensors, Microelectromechanical Systems and Energy Storage and Generation.
The versatility of integrating piezoelectric materials onto an insulating substrate opens up possibilities for innovative solutions in diverse fields, including electronics, energy, healthcare, and more.
