Design and Performance Assessment of a Solid-State Microcooler for Thermal Neuromodulation.It is well known that neural activity can be modulated using a cooling device.  Despite the potential benefits of such technique, its use has been limited due to the lack of suitable thermal modulators.  A miniaturized thermal control solution based exclusively on solid-state devices was designed, occupying only 5 mm × 5 mm × 3 mm, and featuring the potential for wireless power and communications.
