The scientists tell us about their results in the journal Electronics Letters.
The tissue was simulated. The sensor has a side of 1 mm and sits on a circuit board.
before the end should have allowed the researchers fabricate an integrated circuit and planted it in a mouse brain.
Smaller sensors open new possibilities to implant in the body where there is so much space. Small size also makes the implant itself simple.
One electrode is attached to the human body near the implant to send data to and read data from it. Researchers are examining the modulation technique which they will use to broadcast. And they think the lead by more than 2 mm of tissue is possible if the receiver sensitivity adjustment.
Scientists hope it will be possible to plant into several pieces sensors in the human brain for the study of neural interaction.
In the longer term, they fantasize about the direct interface between the brain and the sensor, where the sensor is used unconsciously.
