About

Peng-Fei Li is a leading figure in the field of ferroelectric materials, with a particular focus on organic-inorganic perovskites and their piezoelectric applications. His most celebrated contribution is the discovery of an organic-inorganic perovskite ferroelectric with a large piezoelectric response, published in 2017 and now cited over 1,060 times. This work demonstrated that flexible, mechanically sensitive materials could rival traditional stiff ceramics like BaTiO₃ and PbZrO₃, opening new avenues for wearable and flexible sensor technologies. Building on this, Li’s 2019 study on two-dimensional layered perovskite ferroelectrics achieved a giant piezoelectric voltage coefficient, a critical parameter for high-performance sensors in the Internet of Things era. With over 247 citations, this work also highlighted the importance of a high Curie temperature for practical device stability. Li’s research bridges fundamental materials science and applied engineering, offering solutions for next-generation mechanical sensors. His achievements have positioned him as a key innovator in the development of soft, efficient, and temperature-resilient piezoelectric materials, making significant impacts on both academic research and potential industrial applications.
