Abstract: An integrated GHz ultrasonic neuro-cognitive system including a chip-cyborg having a network of biological neurons that forms a biological information processor, which can be controlled by electronics, optics, and GHz ultrasonic beams. In one example, the chip-scale microsystem includes a CMOS chip with RF CMOS and piezoelectric thin film transducers that can generate GHz ultrasonic waves, which can be phased to form narrow beams, achieving significant ultrasonic intensity to affect neurons. With a sufficient number of ultrasonic pixels, the focal point of the beam can be narrow enough to focus effect specific section of a neuron to enhance or decrease synaptic weights owing to ultrasonic radiation forces and acoustic streaming.

Abstract: A multi-tip nano-probe apparatus and a method for probing a sample while using the multi-tip nano-probe apparatus each employ located over a substrate: (1) an immovable probe tip with respect to the substrate; (2) a movable probe tip with respect to the substrate; and (3) a motion sensor that is coupled with the movable probe tip. The multi-tip nano-probe apparatus and related method provide for improved sample probing due to close coupling of the motion sensor with the movable probe tip, and also retractability of the movable probe tip with respect to the immovable probe tip.
