  • Solving ordinary differential equations (ODE) on the von Neumann architecture normally demands a large amount of computational resources. Yu et al. build ODE solver hardware using a computing-in-memory-based implementation, showing orders of magnitude improvement in energy consumption and speedup.

  • Next-generation human-machine interfaces require efficient physiological signal processing systems. Here, the authors propose a hardware system that uses VO2 memristors to perform brain-like encoding and analysis of physiological signals, and is capable of identifying arrhythmia and epileptic seizures.

  • A highly efficient hardware element capable of sensing and encoding multiple physical signals is still lacking. Here, the authors report a spike-based neuromorphic perception system consisting of tunable and highly uniform artificial sensory neurons based on epitaxial VO2 capable of hand gesture classification.

  • Frequency converters for wireless internet of things applications typically require separate circuits for different functions, causing energy and performance inefficiencies. Using an epitaxially grown VO2 memristor array, Liu et al. present a frequency converter with in-situ frequency synthesis and mix functionality.

  • It is challenging to create efficient and compact neuromorphic sensory system based on nano-scale nonlinear dynamics. Yang et al. present a capacitance-coupled VO2 oscillatory network, which serves as a continuous-time dynamic system for sensory pre-processing, enabling tasks such as touch and gesture recognition.
