Analog–digital hybrid computing with SnS2 memtransistor for low-powered sensor fusion

open access: yesNature Communications, 2022
Analog–digital hybrid computing based on SnS2 memtransistors is demonstrated for lowpower sensor fusion in drones, where a drone with hybrid computing performs sensor fusion with higher energy efficiency than that with only a digital processor.

Enabling Drone Services: Drone Crowdsourcing and Drone Scripting [PDF]

open access: yesIEEE Access, 2019
Drones are rapidly finding their way into civilian applications, and are mostly networked, enabling their remote programming, and connectivity with humans. However, drones are limited by the weight they can carry and battery power resulting in limited resources. Moreover, some applications require utilising multiple drones to act in coordination.
