A method to form a monolithic 3D device including: processing a first layer including first mono-crystal transistors; transferring a second mono-crystal layer on top of the first layer including first mono-crystal transistors by using ion-cut layer transfer; and repairing the damage caused by the ion-cut by using optical annealing. The drivingreceiving unit and the membrane are embodied and matched to one another in such a manner, that the membrane executes only mechanical oscillations, which correspond to modes, which lie above the fundamental mode of the membrane. The hand tool couples with the storage device. Contextually related advertising is then selected based on its relationship to the determined context or topic.
