Prof. Deblina Sarkar was recently interviewed by renowned British comedian Chris McCausland for the BBC documentary Seeing Into the Future, which follows Chris as he explores emerging AI and technological innovations—especially those with the potential to improve life for individuals with visual impairments like his own.

During their conversation, Prof. Sarkar explained about the technology developed in her lab, called Circulatronics, which represents a new generation of autonomous and surgery-free brain-computer interfaces (BCI). These are ultra-small, wireless electronic devices which unlike conventional implants, are engineered to navigate the body’s fluid environments, autonomously target diseased tissue, cross intact blood-brain-barrier and self-implant in the brain without invasive surgical intervention.

Applications of this technology range from vision restoration to the treatment of severe neurological disorders and advanced brain cancers. By reimagining how electronic systems interface with the brain, Circulatronics may enable new therapeutic possibilities while making advanced neurotechnology more accessible.

Although human trials are still approximately three years away, Prof. Sarkar’s animal studies show extraordinary promise. Her research offers genuine hope to Chris and to millions of others seeking solutions to currently untreatable diseases.
