Wireless Tattoo Electronics

In this talk,

I will discuss newly developed technology that uses flexible electronics that can be embedded in a temporary tattoo and placed on the forehead to record neural signals and wirelessly transmit them.  Our approach weds cognitive neuroscience, flexible bio-electronics, and applied mathematics.  I will succinctly discuss how this leads to novel forehead configurations of epidermal electronics for brain monitoring and novel ways to rapidly sequence visual or auditory stimuli for extraction of brain information.  Lastly, I will discuss how our applied math techniques efficiently extract reliable information that closes the feedback loop to guide the subsequent set of stimuli for brain-machine interfaces.  We will discuss applications of this framework that can have implications across society: from education to health to consumer products.  Lastly, I will discuss how the fact that (1) the sensors can be  embedded in a form factor that is mechanically invisible to the user, (2) the sensors can be visually indiscernible to an observer, and (3) the stimuli can be subtly embedded within current forms of media might provide unintended (propitious or ominous) consequences.
