There are two main types of printhead technology, using either heat or a Piezo* element.
All Epson printers use piezo elements. Since they do not heat the ink, piezoelectric systems are compatible with a wide variety of ink and more durable than thermal systems.
Due to this flexibility, Epson printers are known to be used with many different types of ink such as sublimation ink, dye-based ink, pigment-based ink. UV ink, and DTF ink.
What are the other applications that using piezo element?
Piezoelectric materials are used also in a wide range of industries such as automotive, healthcare, telecom, consumer goods, aerospace & defense, and telecommunication.
Examples of other devices rather than printers using piezo element;
What is the piezoelectric made of?
The piezoelectric elements are made of a ceramic. The conventional way to produce the elements was to bake the ceramic like a brick, slice it thinly, and then polish it to the desired thickness. But the ceramic becomes very brittle when baked and the piezoelectric elements would crack or break when reduced below a certain thickness.
How can you overcome this technical issue?
To overcome this technical issue they created piezoelectric elements by stacking many thin layers of approximately 20 micrometers that act like a ceramic capacitor and dicing them into feasible shapes to make an actuator. The thin-form piezo was achieved by creating the multi-layered structure before baking and stacking the piezoelectric elements in strips.
Piezo** is a Greek root meaning pressure or push
