Device for generating ultrasound for use in carbon nano tube velocity microphone for e.g. non-coupled medical therapy, has layer comprising electrical conductive graph structure and conductively connecting two electrodes together

摘要

The device has high frequency sources, and two electrodes, which are attached at the high frequency sources. A layer comprises an electrical conductive graph structure and conductively connects the two electrodes together. The graph structure is provided in a form of a freely carrying planar bucky paper layer (11) and comprises disordered or ordered or combed single-wall and/or multi-wall carbon nano tubes. The graph structure is contacted and/or attached at metallic functional layers of a substrate e.g. silicon or silicon nitride, by wire bonding techniques by openings (14). Independent claims are also included for the following: (1) a probe for non-destructive material testing with ultrasound and/or for medical ultrasound applications (2) a method for non-destructive material testing for medical diagnosis or therapy.
