Neural recording systems are vital tools for acquiring and processing brain signals. Scientists at the A*STAR Institute of Microelectronics, Nanyang Technological University and the National University of Singapore have developed an integrated circuit chip that offers record-low power consumption for direct recording of brain activities.

The implantable system, which comprises multiple electrodes for data acquisition, promises to minimise a patient’s exposure to electromagnetic radiation and heat during the recording process, making it possible to integrate more than 100 channels to acquire a more comprehensive profile of brain signals.

“This power-efficient device will enable new possibilities for the development of implantable brain interfaces, allowing paralysed patients to control wheelchairs or robotic arms with their minds,” says Associate Professor Gavin Dawe of the National University of Singapore and Singapore Institute for Neurotechnology. So far it has been used to record the brain activity of an anaesthetised rat, bringing it one step closer to clinical deployment.
