Powering brain implants without wires with thin-film wireless power.

Posted in Science on 9th Feb, 2016 06:44 PM by AlexMuller

An implanted wireless power transmission (WPT) device can deliver power to an implanted neural interface system, such as a brain-computer interface (BCI).The system avoids having to connect an implanted device to an external power source via wires through a hole in the skull, which can cause infections.

 
The system also allows for free-moving subjects, allowing for more natural behavior in experiments. The researchers used a wafer-level packaging technique to integrate a silicon large-scale integration (LSI) chip in a thin (5 micrometers), flexible parylene film, using flip-chip (face-down) bonding to the film.
 
The system includes a thin-film antenna and a rectifier to convert a radio-frequency signal to DC voltage (similar to how an RFID chip works). The entire system measures 27 mm × 5 mm, and the flexible film can conform to the surface of the brain.
 
The researchers plan to integrate additional functions, including amplifiers, analog-to-digital converters, signal processors, and  a radio frequency circuit for transmitting (and receiving) data.
 
Such a system could perform some of the functions of the Braingate system, which allows paralyzed patients to communicate
