Highly durable intrinsically stretchable neuromorphic devices (ISNDs) achieve 10^5 cycles at 50% strain. Molecular control of polymer chain stacking enhances mechanical reliability for wearable computing.

Area of Science:

  • Materials Science
  • Electronics
  • Artificial Intelligence

Background:

  • Intrinsically stretchable neuromorphic devices (ISNDs) are crucial for wearable computing.
  • Conventional ISNDs suffer from limited mechanical durability and electrical degradation under strain.
  • Existing strategies often compromise device performance for stretchability.

Purpose of the Study:

  • To develop highly durable ISNDs with enhanced mechanical stability and sustained electrical performance.
  • To investigate a molecular design strategy for improving the morphology and reliability of semiconducting polymers in stretchable devices.
  • To demonstrate the practical application of these durable ISNDs in on-device artificial intelligence.

Main Methods:

  • Incorporated a microstructure-controlling moiety into the polymer backbone to modulate chain stacking.
