Waterproof Electronic-Bandage with Tunable Sensitivity for Wearable Strain Sensors
We demonstrate high-performance wearable
electronic-bandage (E-bandage) based on carbon nanotube (CNT)/silver
nanoparticle (AgNP) composites covered with flexible media of fluoropolymer-coated
polydimethylsiloxane (PDMS) films. The E-bandage can be used for motion-related
sensors by directly attaching them to human skin, which achieves a
fast and accurate electric response with high sensitivity according
to the bending and stretching movements that induce changes in the
conductivity. This advance in the E-bandage is realized as a result
of the sensitivity that can be achieved by controlling the concentration
of AgNPs in CNT pastes and by modifying the device architecture. The
fluoropolymer encapsulation with hydrophobic surface characteristics
allows for the E-bandage to operate in water and protects it from
physical and chemical contact with the daily life conditions of the
human skin. The reliability and scalability of the E-bandage as well
as the compatibility with conventional microfabrication allow new
possibilities to integrate flexible human-interactive nanoelectronics
into mobile health-care monitoring systems combined with Internet
of things (IoTs)
