Integrating interactive interfaces into everyday objects is essential for bridging the gap between the digital and physical worlds. However, many existing interface technologies are bulky and challenging to seamlessly integrate into the environment. This work introduces eStone, an approach that utilizes natural stone surfaces as substrates for capacitive thin-film sensors, turning them into interactive interfaces. Metallic thin films, such as 200 nm-thick aluminum, were sputter-deposited and structured on various stones, including marble, granite, porphyry, and limestone, to create conductive patterns that enable the formation of capacitive sensors. <\/p>\n\n\n\n

The nanometer-scale thickness of these layers maintains the stone’s natural appearance and texture while making them functional and durable capacitive sensors. Coupled with through-hole contacting vias and customized conventional readout electronics, eStone demonstrates high performance when used as a capacitive controller for tasks such as adjusting a loudspeaker’s volume or a thermostat’s temperature.<\/p>\n\n\n\n
