脑机接口设计过程中的一个主要障碍是无法获得一种大规模的、无线的、自我供电的、持久的神经植入式设备。目前最先进的植入式设备受到各种限制。基于电磁的无线设备体积很大，因为它们的天线很大，必须大于工作频率波长的十分之一。基于超声波的无线设备，除了它们的低数据速率外，在头骨中有大量的损失，并且需要在头骨下有一个中间的电磁收发器。此外，几乎所有最先进的无线设备都使用微电极来记录神经元，由于组织与金属电极之间的直接接触，这在长期监测应用中并不可靠。在本文中，我们提出了一种新颖的、无线的、超紧凑的植入型设备，称为纳米神经RFID。在这个装置的核心，有一个磁电(ME)天线阵列。ME天线智能且超小型化(
A major obstacle during the design of brain-computer interfaces is the unavailability of a neural implantable device that is mu-scale in size and is wireless, self-powered, and long-lasting. The current state-of-the-art implantable devices suffer from various limitations. Electromagnetic-based wireless devices are big in size because of their large antenna, which must be larger than one-tenth of the wavelength of the operational frequency. Ultrasound-based wireless devices, in addition to their low data rate, have massive loss in the skull and need an intermediate electromagnetic transceiver under the skull. Furthermore, almost all state-of-the-art wireless devices use micro-electrodes for neuronal recording, which are not reliable in long-term monitoring applications because of the direct contact between the tissue and metal electrodes. In this paper, we propose a novel, wireless, and ultra-compact implantable device termed NanoNeuroRFID. At the core of this device, there is a magnetoelectric (ME) antenna array. ME antennas are smart and ultra-miniaturized (
