Flexible and scalable sensor arrays for recording and modulating physiological activity
First Claim
1. An implantable cortical surface electrode array, comprising:
- a flexible substrate adapted for implantation in a tissue of a patient and adapted to conform to a cortical surface;
an array of electrodes arranged on said flexible substrate; and
switches incorporated into said flexible substrate, said switches arranged between adjacent electrodes so as to selectively connect respective individual electrodes to each other so as to enable effective size, configuration, and number of electrodes to be dynamically changed.

Abstract
An implantable sensor array incorporates active electronic elements to greatly increase the number of sensors and their density that can be simultaneously recorded and activated. The sensors can be of various configurations and types, for example: optical, chemical, temperature, pressure or other sensors including effectors for applying signals to surrounding tissues. The sensors/effectors are arranged on a flexible and stretchable substrate with incorporated active components that allow the effective size, configuration, number and pattern of sensors/effectors to be dynamically changed, as needed, through a wired or wireless means of communication. Active processing allows many channels to be combined either through analog or digital means such that the number of wires exiting the array can be substantially reduced compared to the number of sensors/effectors on the array.
