Abstract

We report a novel interdigital sensor and actuator device based on branched treelike carbon nanotubes (CNT) on silicon-based membranes with an ultra high capacitance value. The presence of treelike CNTs leads to a high overlap between interdigital fingers as well as high electron emission thanks to many nanometric branches attached to their central stem. The fabricated B-CNT-based device resulted in a high capacitance value in comparison to typical devices, leading to a stronger electromechanical coupling behavior. The electro-mechanical behavior of the device has been investigated both with electron emission and capacitive characteristic of the sensor, which confirm superior performance of the investigated devices over silicon-based devices.
