In one aspect, an apparatus for stimulating and/or monitoring a nerve is described herein. In some embodiments, the apparatus comprises a top substrate layer, a bottom substrate layer in facing opposition to the top substrate layer, and a channel disposed between the top substrate layer and the bottom substrate layer. The apparatus further comprises a plurality of electrodes disposed on one or more interior surfaces of the channel. Additionally, the channel is defined by the top substrate layer, the bottom substrate layer, and a retaining wall extending at least partially between the top substrate layer and the bottom substrate layer. The retaining wall retains the nerve within the channel.

Apparatus and method for nerve stimulation and/or monitoring

A regenerative interface electrode comprising a multilayer or sandwiched stack of dies that are oriented at their distal ends with at least one layer inset such that it forms a groove into which a nerve may be positioned inside the groove. The die layers include electrodes that connect to the nerve, allowing the nerve to be modulated. The electrodes in the die layers are connected to a PCB, which may communicate with a recording device. The distal end of the sandwiched die layers forming the groove is inserted into a nerve tube, into which the nerve is inserted.

Regenerative interface electrode

This disclosure includes electrohydrodynamic (EHD) printer nozzles, associated printer heads and printers, and methods for using the same. Some EHD nozzles include a circuit with at least one depressible electrical connector and a housing configured to receive a dispensing device such that electrical communication is permitted between the at least one depressible electrical connector and a conductive tip of the dispensing device, where the housing is further configured to be releasably coupled to a printer head such that voltage can be applied across the conductive tip. Some nozzles include an additional electrode. Some of the present methods include inserting a dispensing device into an EHD nozzle having a housing with a depressible electrical connector such that the connector contacts a conductive tip of the dispensing device and applying a voltage across the conductive tip. Others of the present methods include performing maskless lithography with the present EHD printers and components.
