About

Samuel Peana is a pioneering researcher at the forefront of micro-robotics and functional oxide thin films, with a specialized focus on perovskite nickelate materials. His most cited work, "Perovskite Nickelate Actuators" (2021, 9 citations), introduces neodymium nickelate (NdNiO₃) thin films as a transformative actuator material for micro-robotic systems. This contribution addresses a critical bottleneck in the field—efficient, scalable actuation—by leveraging the unique phase-change properties of nickelates to produce large, reversible mechanical responses. Peana’s research bridges materials science and micro-engineering, offering a pathway toward applications in search and rescue, smart dust, advanced additive manufacturing, and micro-surgery. By demonstrating that perovskite nickelates can serve as high-performance actuators, he has opened new avenues for designing untethered, energy-efficient micro-robots. His work stands out for its interdisciplinary impact, merging solid-state chemistry with robotics to solve real-world miniaturization challenges. With a growing citation footprint, Peana is establishing himself as a key figure in the next generation of micro-robotic materials, pushing the boundaries of what is possible at the microscale.
