Conventional materials are reaching their limits in computation, sensing, and data storage capabilities, ushered in by the end of Moore's law, myriad sensing applications, and the continuing exponential rise in worldwide data storage demand. Conventional materials are also limited by the controlled environments in which they must operate, their high energy consumption, and their limited capacity to perform simultaneous, integrated sensing, computation, and data storage and retrieval. In contrast, the human brain is capable of multimodal sensing, complex computation, and both short- and long-term data storage simultaneously, with near instantaneous rate of recall, seamless integration, and minimal energy consumption. Motivated by the brain and the need for revolutionary new computing materials, we recently proposed the data-driven materials discovery framework, . This framework aims to mimic the brain's capabilities for integrated sensing, computation, and data storage by programming excitonic, phononic, photonic, and dynamic structural nanoscale materials, without attempting to mimic the unknown implementational details of the brain. If realized, such materials would offer transformative opportunities for distributed, multimodal sensing, computation, and data storage in an integrated manner in biological and other nonconventional environments, including interfacing with biological sensors and computers such as the brain itself.
传统材料在计算、传感和数据存储能力方面已经达到极限,这是由摩尔定律的终结、无数传感应用以及全球数据存储需求的持续指数增长所带来的。传统材料还受到其必须运行的受控环境、高能耗以及同时进行传感、计算以及数据存储和检索的有限能力的限制。相比之下,人脑能够进行多模态传感、复杂计算以及短期和长期的数据存储,具有近乎即时的回忆速度、无缝集成和最小的能耗。受大脑和对革命性新型计算材料的需求的启发,我们最近提出了数据驱动的材料发现框架。该框架旨在通过编程激子、声子、光子和动态结构纳米材料来模拟大脑的集成传感、计算和数据存储能力,而不试图模拟大脑未知的实施细节。如果实现,这些材料将为在生物和其他非传统环境中以分布式、多模态方式进行传感、计算和数据存储提供变革性机会,包括与大脑等生物传感器和计算机进行接口。
