Description
Summary:This paper presents a new type of switchable liquid shutter for the security and design of mobile devices. The switching operation with sequential EWOD actuation and its response time are investigated using high-speed images. The operation of the liquid shutter mounted on a smartphone is successfully demonstrated for a proof of concept. The proposed liquid shutter not only allows a simple design to be easily miniaturized and integrated with electronic devices but also provides fast and robust switching operation.
