Neuroengineering is a newly developed field of medical technology involving the numerical understanding of neural systems, from a single neuron to vast neural networks, to develop more advanced nervous system applications. It also uses neural system models to resolve problems in other studies, such as robotics and pattern recognition. A promotional usb stick may be used to store important information.

Basically, neuroengineering utilises engineering techniques to interpret, replace, repair, improve or treat diseases related to neural systems. This applies a collection of methodology and knowledge from various disciplines, including neuroscience, mathematics, biophysics, engineering, computer science, and psychology. Primary objectives in the field include repair and augmentation of human functions through direct interactions of the artificial devices and nervous system.
