Background:

Wearable bioelectronics require skin adhesion but face challenges with sweat accumulation.
Conventional porous materials limit device versatility and breathability.

Purpose of the Study:

To develop a sweat-removable skin sticker (SRSS) with enhanced breathability for wearable bioelectronics.
To maintain robust skin adhesion and functional versatility through a novel channel architecture.

Main Methods:

Fabrication of SRSS using a hybrid process involving direct ink writing (DIW).
Creation of a hierarchical trichome-inspired microchannel architecture for rapid sweat removal.
Integration of multi-level ribs design for optimized water removal.

Main Results:

SRSS demonstrated a water removal rate of 25.6 ml/cm²/min, significantly exceeding human sweat secretion rates.
The channel-based adhesive interface design is compatible with attached wearable bioelectronics, like temperature sensors.
Achieved rapid sweat removal, reducing accumulation and enhancing user comfort.

Conclusions:

The developed SRSS offers a structurally engineered, permeable bioadhesive interface for advanced wearable bioelectronics.
This innovation addresses the critical challenge of sweat management in skin-adherent devices.
The trichome-inspired design provides a versatile solution for improving the performance and wearability of bioelectronic systems.
