On March 30th, according to a report from CCTV News, the latest issue of "Science" published an article titled "Biodegradable Ferroelectric Molecular Crystals with Large Piezoelectric Response", which was completed by a team from Southeast University.
For the first time, researchers have combined ferroelectric chemistry with bioelectronics, innovatively developing a biodegradable organic ferroelectric crystal that matches the piezoelectric response of inorganic ceramic barium titanate (BTO).
This marks a milestone breakthrough since the discovery of the piezoelectric effect by the Curie brothers in 1880.
Piezoelectric materials are a class of functional materials that can convert mechanical stress into electrical signals.
Currently, inorganic piezoelectric ceramics and piezoelectric polymers dominate applications, but they are not biodegradable. Therefore, implantable electronic devices made from these traditional piezoelectric materials face the risk of secondary surgery for removal from the human body.
Implantable transient electronic devices based on biodegradable materials are expected to bring significant changes to the medical field.
According to reports, molecular ferroelectric materials have unique advantages such as simple synthesis, easy processing, lightweight, good biocompatibility, and tunable physical properties, making them ideal candidates for implantable transient electronic devices.
Therefore, there is an urgent need to develop biodegradable molecular ferroelectric materials with high piezoelectricity.
The reviewers of "Science" highly praised this work, believing it to be a key breakthrough in the field of transiently implantable piezoelectric materials.
