A flexible printed circuit board (FPCA) of a brain computer interface (BCI) module is configured to interconnect a plurality of emitter assemblies and a plurality of detector assemblies of the BCI module. The FPCA comprises a connector portion for connecting the FPCA to a controller of the BCI module, a plurality of rigid sections, a plurality of flexible sections. A first subset of rigid sections is configured to mount the plurality of emitter assemblies. A second subset of rigid sections is configured to mount the plurality of detector assemblies. Each flexible section is configured to attach the two or more rigid sections of the plurality of rigid sections to each other. The plurality of flexible sections allows the plurality of emitter assemblies and the plurality of detector assemblies to stretch to conform to a head of a user.

Flexible circuit board design in a brain computer interface module

A ferrule is configured to optically coupled to electronics for detect signals from a head of a user. The ferrule has optical properties to guide light between the electronics and a head of a user. The ferrule comprises a base portion having a cavity to enclose an optical element, a middle portion configured to guide light to or from the optical element, and a tip portion to interface with the head of the user.

Ferrule design for a brain computer interface module

A brain computer interface (BCI) module includes a flexible printed circuit assembly (FPCA) configured to conform to the head of a user. A plurality of emitters and a plurality of detectors are mounted on the FPCA. Each emitter of the plurality is configured to emit light towards the head of the user and each detector is configured to detect the emitted light. An array of ferrules is additionally mounted to the FPCA such that each ferrule of the array encases an emitter or a detector. The BCI module additionally includes a controller that is configured to receive an optical signal detected by a detector of the plurality and to encode the detected signal into a biological signal.

Brain computer interface architecture

A brain computer interface system includes a retainer and cap assembly for transmitting light to a user's head region and transmitting optical signals from the user's head region to a detector subsystem. The retainer is configured to secure the cap assembly to a head region of a user. The cap assembly includes an array of ports that retain an array of ferrules. A first ferrule in the array of ferrules can include a channel that extends at least partially through the body of the ferrule. The channel retains a fiber optic cable such that the fiber optic cable is in communication with a head region of a user during a mode of operation. The cap includes an elastic portion such that in a mode of operation, the cap and array of ferrules are biased towards the head region of a user.
