Latest Patents

Among his recent inventions, Wang has created two noteworthy patents. The first is **Wafer-scale piezoelectric bio-organic thin films**. This invention involves a flexible piezoelectric thin film constructed from a polyvinyl alcohol (PVA)-glycine-PVA sandwich heterostructure. The unique fabrication method allows the film to automatically assemble as the solvent is evaporated from a glycine-PVA mixture solution. The strong hydrogen bonding between glycine and PVA chains enables the nucleation of piezoelectric γ-glycine, resulting in enhanced domain orientation.

The second innovative patent is a **3D-printed ferroelectric metamaterial with giant piezoelectricity and biomimetic mechanical toughness**. This invention presents an in-situ poled ferroelectric that is printed in a true 3D geometry and features an intercalated electrode design. Soft polymer matrices are used for the ferroelectric layers, while rigid matrices are utilized for the electrode layers, mimicking the structure of nacre. This design not only demonstrates ceramic-like piezoelectric properties but also exhibits bone-like fracture toughness. Additionally, lithium-doped potassium sodium niobite (Li—KNN) microparticles are employed to enhance ferroelectric properties and ensure robust interfacial bonding.
