Printed degradable piezoelectric microsystems: From ink formulation to device fabrication and characterization

Morgan Mc Kay Monroe

As the world moves further and further into the semiconductor era, the amount of waste generated from electronics ("e-waste") is increasing rapidly and unsustainably. Of particular note, alternatives to lead-based piezoelectric materials must be establishe ...
