Abstract
In one aspect, the present disclosure provides organic semiconductors (OSNTs) as well as high-performance electrochemical devices based on the present OSNTs for the production of micro and nano-scale actuators. The present OSNTs may be used in several applications, including movable and implantable interface devices, such as flexible neural microelectrodes. Also provided herein are flexible neural microelectrodes based on conjugated polymer actuators.
Claims12
A neural probe device comprising:
- a proximal portion;
- a shank extending from the proximal portion along a longitudinal axis;
- and
- at least one movable projection disposed along the shank comprising a rectangular segment and a rounded tip comprising a recording site for signal recording,
- wherein the rectangular segment is formed from an organic semiconductor nanotube (OSNT) comprising at least one conducting polymer and polystyrene sulfonate (PSS) such that the OSNT on the rectangular segment bends transversely to the longitudinal axis of the shank in response to an applied voltage.
