Monolithic pixel sensors integrate the sensing layer and readout electronics on a single silicon substrate, eliminating the need for interconnects and enabling cost-effective production using CMOS technology. This lecture covers the evolution of monolithic pixel sensors, focusing on key technical challenges in embedding readout electronics and recent advancements. The ALPIDE sensor, used in the ALICE Inner Tracking System (ITS), represents the state of the art in monolithic integration, offering high granularity and low material budget, with ongoing developments targeting wafer-scale stitched sensors. The MONOLITH project aims to push timing resolution to sub-10 ps by employing a SiGe BiCMOS process and the innovative PicoAD continuous gain layer. Applications beyond particle physics will also be discussed, including high-resolution PET imaging for medical diagnostics and time-of-flight (ToF) LiDAR for depth sensing..
