Neuromorphic Memory Devices

  • The Von Neumann computer only can do well-structured mathematical calculation. The brain, However, can make proper decision under unfamiliar situations based on the past experience and memory consuming 20 Watt so that the brain have been attracting as a biological model to make the energy-efficient cognitive computing system.

  • Given that photonic neuromorphic devices opens the door of opportunities for the mimicry of learning and memory function with the ultrafast operating speed and broad bandwidth for applications in cognitive computing system.

Metal-Oxide Thin-Film Transistors

  • Metal-oxide based electronics have gained a significant interest in flexible and transparent electronics owing to their outstanding electrical performance and high optical transparency.

  • Solution-based deposition of metal-oxide films is favorable for ambient deposition, low-temperature processing, and roll-to-roll fabrication of metal-oxide-based flexible electronics.

  • We have investigated photochemical activation annealing to convert the as-spun precursor film into a functional and dense metal-oxide layer for flexible electronics.

Wearable/Stretchable Electronics

ACS Appl. Mater. Interfaces 2017, 9, 10190-10197

  • Fabrics are flexible, stretchable and comfortable with clothing and can be used in clothing as well as bedding, carpet, and curtain

  • Our aim is to realize the wearable electronics that are closer to daily life using yarns and fabrics.

  • We have investigated wearable electronics such as textile-based wearable devices especially wearable sensors with functional fibers and ultra-long metallic nanowires synthesis which can be applicable to various types of electrode for wearable electronics.
