Abstract

The Internet of Bio-Nano Things in the Brain are minimally invasive untethered links between the brain tissue and silicon platforms. Even though these interfaces have been envisioned for many biomedical applications, it is unclear how the ultimate technology will support spatially distributed networks. In this paper, we address the distributed power allocation through adaptable beamforming by varying the acoustic beam lateral resolution. Our results show improvements in average power transfer efficiency for sparser beams compared to narrower ones for a randomly placed network of implantable devices with 15 nodes within a 4mm2 space in the neocortex.

一种适用于大脑中生物纳米物联网的自适应横向分辨率声学波束形成

大脑中的生物纳米物联网是大脑组织和硅平台之间的微创无连接。尽管这些接口已被设想用于许多生物医学应用，但尚不清楚最终技术将如何支持空间分布式网络。在本文中，我们通过改变声束横向分辨率，通过自适应波束形成来解决分布式功率分配问题。我们的结果显示，与新皮质4mm2空间内有15个节点的可植入设备随机放置网络的窄波束相比，稀疏波束的平均功率传输效率有所提高。

期刊介绍： As a result of recent advances in MEMS/NEMS and systems biology, as well as the emergence of synthetic bacteria and lab/process-on-a-chip techniques, it is now possible to design chemical “circuits”, custom organisms, micro/nanoscale swarms of devices, and a host of other new systems. This success opens up a new frontier for interdisciplinary communications techniques using chemistry, biology, and other principles that have not been considered in the communications literature. The IEEE Transactions on Molecular, Biological, and Multi-Scale Communications (T-MBMSC) is devoted to the principles, design, and analysis of communication systems that use physics beyond classical electromagnetism. This includes molecular, quantum, and other physical, chemical and biological techniques; as well as new communication techniques at small scales or across multiple scales (e.g., nano to micro to macro; note that strictly nanoscale systems, 1-100 nm, are outside the scope of this journal). Original research articles on one or more of the following topics are within scope: mathematical modeling, information/communication and network theoretic analysis, standardization and industrial applications, and analytical or experimental studies on communication processes or networks in biology. Contributions on related topics may also be considered for publication. Contributions from researchers outside the IEEE’s typical audience are encouraged.
