Implantable Microelectronic Devices
We are working on the implantable electronic technologies for brain implantable devices including encapsulation and neural electrodes fabrication. Our research also develops miniaturised highly sensitive magnetic devices for the next generation of wearable and implantable Magnetomyography (MMG) and Magnetoencephalography (MEG). The figure below simplifies our research on developing devices to be implemented in the brain and skeletal muscle.
