Bioinspired Hierarchical Architecture with Water Transport Channels for Strong Adhesion at the Sweating Interface
First student author · Co-first author
Overview
Can a skin patch remove sweat through its thickness while preserving adhesion and stable electrical contact?
My Work
Interface architecture
Integrate bioinspired adhesive microstructures with tapered transport channels to balance conformal skin contact and sweat drainage.
Transport mechanism
Analyze capillary transport and compare smooth, single-groove and double-groove channels through modelling and liquid-flow observations.
Wearable validation
Validate attachment on curved and wet skin, permeability and ECG/EMG monitoring during motion and under applied loads.
Capillary channel design
Tapered channels and internal grooves guide liquid away from the adhesive interface.
Conformal contact and wet-skin adhesion
Tests examine attachment on curved skin and under movement and applied load.
Permeability and skin response
Thermal imaging and water-loss measurements assess the effect of transport channels on the skin interface.
ECG and EMG validation
The patch is evaluated as a wearable interface for biosignal recording under wet conditions and different physical loads.
