摘　　要：Water droplets help life in nature survive,thrive,and evolve.With water droplet serv-ing as one of the indispensable elements in the Internet of Things(IoT),many droplet-oriented technologies,such as microfluidics,droplet manipulation,electrowetting,and energy harvesting,make rapid progress driven by material science,computer science,and medicine.Droplet-based wearable devices are endowed with advantages such as flexibility,sensing ability,and automation for various parameter detection.Besides,the continuous exploration of droplet manipulation has led to the emergence of a wide variety of manipulation methods.Meanwhile,electrowetting that utilizes exter-nal fields modifying liquid–solid surfaces has found its applications in various areas,including droplet transportation,microfabrication,and healthcare.The energy gener-ation from water droplets also presents exciting opportunities for the development of novel electricity generators.These approaches for droplet utilization underscore the immense potentials and versatilities of droplet-based technologies in the IoT land-scape.Hence,this mini review presents the fundamental droplet-based technologies by summarizing their working mechanisms and methods,device structures,and appli-cations.Given the challenges in materials,fabrication,and system integration,this review shows the overall development roadmap in terms of improved functionality and performance and highlights the opportunities toward multifunctional,self-sustainable,and intelligent systems,which is called for IoT construction.
