Humidity-Independent Ion Gel System

This technology describes a humidity-independent ion gel system, which consists of an ion gel laminate composed of a hydrophobic ion gel layer and a hydrogel layer, encapsulated by a sealing film, along with its manufacturing method.

Conventional ion gels suffered from changes in electrical properties when exposed to humidity variations due to their hygroscopic nature.

This technology, with its hydrophobic ion gel layer and sealing film structure, blocks the effects of humidity and deformation, enabling stable temperature sensing for extended periods, and is applicable to portable and skin-attachable devices.

Key Features:
  • Ion gel laminate comprising a hydrophobic ion gel layer and a hydrogel layer
  • Sealing film encapsulating the laminate
  • Structure unaffected by humidity and deformation
  • Stable temperature sensing for extended periods and applicability to wearables
