Fruit flies have been an useful animal model for studying genomics. However, observing and analysing the fly behaviours are labour-intensive and time-consuming. This research exploits the Low-Temperature-Poly-Silicon (LTPS) technology to implement a neuromorphic micro-system for monitoring fly behaviours automatically. The system integrates photodiodes, adaptive pixel circuits, and event-triggered address-reporting circuits on a glass substrate. With a chip area greater than 1cm2, flies can move freely above the chip and their positions can be detected and reported automatically.
