DOI: 10.1126/sciadv.aef9861 Scientists have developed a new way to make ceramic materials that can better withstand extreme heat and continue performing reliably in sensors and actuators. The approach creates tiny structures throughout the material that give it new electrical and mechanical properties.
The international team has created what they describe as "bulk ferroelectric heterostructures" within a lead-free bismuth ferrite-barium titanate ceramic.
