About
Donald P. Butler is a prominent researcher specializing in flexible electronics, microelectromechanical systems (MEMS), and advanced sensing technologies, with a particular focus on applications in robotics and prosthetics. His work has made significant contributions to the development of next-generation tactile and motion sensing systems that push the boundaries of what wearable and robotic technology can achieve. Butler's most celebrated contribution involves pioneering self-powered tactile pressure sensors utilizing ordered crystalline zinc oxide (ZnO) nanorods fabricated on flexible substrates. This innovative work, which has garnered 47 citations, demonstrated high-resolution spatial pressure detection at 1 mm or better — a breakthrough for robotic skin and multifunctional sensing garments. By harnessing the piezoelectric properties of ZnO nanorod arrays, his sensors operate without external power sources, representing a major step toward truly autonomous robotic systems. Beyond tactile sensing, Butler has advanced flexible MEMS accelerometer technology, developing wafer-level packaged devices capable of monitoring motion and orientation in robotic and prosthetic applications. His holistic approach — spanning nanomaterial synthesis, device fabrication, and real-world application — reflects a commitment to translational research that bridges laboratory innovation and practical human-centered technology. His work continues to influence the fields of soft robotics, prosthetics, and wearable sensing systems.
