我们报告了我们的初步工作，探索一种新的信号传输方法的生物植入式微系统。脑内通信（IBCOM）是一种无线信号传输方法，它利用大脑本身作为传导介质，在神经植入物和大脑外的数据处理系统之间传输数据和命令。设计并制作了两个小型化的IBCOM (mu-IBCOM) CMOS芯片，在体内实验平台上以不同的二进制移频键控（BFSK）载波频率传输两个预先录制的神经信号，验证了IBCOM概念的可行性。除了外部供电外，这些芯片被包装成可以完全植入大鼠大脑。在距离为15mm的两个铂电极之间，以小于650 pJ/bit的传输功率传输神经信号波形，成功恢复了原始神经信号波形。
We report our preliminary work to explore a new method of signal transmission for bio-implantable microsystems. Intra-brain communication or IBCOM is a wireless signal transmission method that uses the brain itself as a conductive medium to transmit the data and commands between neural implants and data processing systems outside the brain. Two miniaturized IBCOM (mu-IBCOM) CMOS chips were designed and fabricated for an in vivo test bed to transmit two prerecorded neural signals at different binary frequency shift keying (BFSK) carrier frequencies to validate the feasibility of IBCOM concept. The chips were packaged for full implantation in a rat brain except for external power delivery. The original neural signal waveforms were successfully recovered after being transmitted between two platinum electrodes separated by 15 mm with transmission power less than 650 pJ/bit for the CMOS implementation.
