Leon Chua

Definition

Leon Chua is an influential electrical engineer and professor known for his pioneering work in the field of memristors, which are two-terminal non-volatile memory devices that can change resistance based on the history of voltage and current. He introduced the concept of the memristor in 1971, establishing a new fundamental circuit element alongside resistors, capacitors, and inductors. Chua's work laid the groundwork for exploring the potential applications of memristors in neuromorphic computing and resistive switching devices.
