A new electronic implant has been developed to provide a non-invasive solution for tracking brain activity. The ‘electronic tattoos’ are applied using a microjet printer and can last up to six hours, making them more comfortable and longer-lasting than traditional electrodes.
Electronic ‘tattoos’ offer an alternative to electrodes for brain monitoring. Traditional electrodes can be uncomfortable and restrictive, causing consternation during medical tests. They rely on glue to stay in place, which can dry out and cause issues. Additionally, hair can stymie electrode contact, making it difficult to get accurate readings.
The electronic ‘tattoos’ are applied using a microjet printer, which sprays the ink onto precise spots on the scalp. The liquid ink contains polymers that can carry electrical signals and oozes around hair to settle directly on the skin of the scalp before drying.
They can be applied wet, making them easier to use
They last longer than traditional electrodes, with most data still accurate after six hours
They are more comfortable and less restrictive
The new method has potential applications in various fields, including neuroscience, medicine, and computer science. It could be used to diagnose conditions such as epilepsy, brain injuries, and sleep disorders.
Further research is needed to explore the possibilities of this technology. The researchers suggest testing the e-tattoos on people with different hair types and exploring other potential uses for the technology, such as monitoring heart activity or muscle movement.
