Description

The objective of this WP is to design and to fabricate an ASIC for the recording of nerve signals with conduction velocity selectivity and a bi-directional digital communication port. This ASIC will be integrated in an implanted (encapsulation by AML) stimulating electrode (artefact rejection problem). This WP will also tackle the problem of the distal power supply.

For this WP, UBATH spent efforts on specifying the detailed design of the amplifier and on resolving issues concerning the identified technologies for the recording system. At GREN, a recording system was initially set up and tested on frog sciatic nerves and an in vivo vagus stimulation is later installed for the tests.

The figure below illustrates an example of final demostrators.
