In order to achieve wirelessly operating wearable bio-environmental sensors, we do the research on energy generating devices
such as flexible solar cells and wireless power receiving devices.
To develop high-performance wearable solar cell, mechanically vulnerable ITO electrodes would be replaced with a transparent,
conductive polymer(PEI, PEDOT:PSS)/conductive nanomaterials composite. Conductive nanomaterials with high transparency
and mechanical strength include conductive metal oxide nanoparticles, nanorods, metal nanowire, carbon nanotubes, and
graphene. Based on these strain-stable transparent electrodes, we will develop highly efficient thin-film solar cell with next
generation light absorbent, metal halide perovskite.
We design the serpentine antenna which can be integrated into stretchable, skin-attachable, wirelessly-charged energy storage
system. The resonance frequency of the antenna will be adjusted to the NFC standard frequency, 13.56 MHz, and then the
antenna would be transplanted on to thin, flexible polymer film to produce stretchable/wearable wireless power receiver.
