RIGID STIFFENER-REINFORCED FLEXIBLE NEURAL PROBES, AND METHODS OF FABRICATION USING WICKING CHANNEL-DISTRIBUTED ADHESIVES AND TISSUE INSERTION AND EXTRACTION

摘要

A stiffener-reinforced microelectrode array probe and fabrication method using wicking channel-distributed adhesives which temporarily adheres a flexible device onto a rigid stiffener for insertion and extraction. Assembly is by dispensing a liquid adhesive into a narrow open groove wicking channel formed on the stiffener so that the adhesive is wicked along and tills the channel by capillary action, and adhering the adhesive-filled bonding side of the elongated section of the rigid substrate to a flexible device.

1. A method of assembling a rigid substrate onto a flexible device comprising:
providing a rigid substrate (i.e. stiffener) having an elongated section, and a narrow open groove channel formed on a bonding side of the elongated section; dispensing a liquid adhesive into the narrow open groove channel so that the adhesive is wicked along and fills the narrow open groove channel by capillary action; and adhering the adhesive-filled bonding side of the elongated section of the rigid substrate to a flexible device.
