About

Wei-Qiang Liao is a leading figure in the discovery and design of molecular ferroelectrics—a class of flexible, lightweight materials that could replace rigid ceramics in next-generation sensors and memory devices. His groundbreaking 2017 work identified an organic-inorganic perovskite ferroelectric with a large piezoelectric response, achieving over 1,060 citations for demonstrating that soft, solution-processable materials can rival the performance of traditional ceramics like BaTiO₃. This breakthrough opened new avenues for wearable mechanical sensors and energy harvesters. Liao further advanced the field by engineering an above-room-temperature molecular ferroelectric, [Cyclopentylammonium]₂CdBr₄, which overcame a critical barrier by maintaining ferroelectric stability at practical operating temperatures. His research systematically addresses the challenge of structural adjustability in molecular crystals, using chemical design to tune properties such as polarization and phase-transition temperatures. With a citation impact exceeding 1,100 for his most influential works, Liao’s contributions are shaping the future of smart materials, offering a sustainable, flexible alternative to conventional inorganics for electronics and sensing technologies.
