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, autonomous computing materials. 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.
