발표초록 : 

The efforts to learn and take inspiration from nature have proven successful in a wide range of areas such as epidermal electronics, dry adhesion, optical systems and biomimetic materials. Here, we report that the wing locking device of beetles can be exploited to form a reversible interlocker based on van der Waals force-assisted binding between high aspect-ratio polymer hairs. For potential applications to multifunctional mechano-sensitive devices, the assembled device demonstrates an excellent gauge factor of ~11.45 and can measure simultaneously three different mechanical stimuli such as pressure, shear force, and torsion with high sensitivity and wide dynamic range. In advance, we present a simple wearable bandage-like capacitive pressure sensor, which adopted bio-inspired designs to achieve ultra-conformity on non-flat surfaces and substantial enhancement in the signal-to-noise ratio of the retrieved signals from the human body. It is demonstrated that the waveforms retrieved from a healthy subject and a person with cardiac diseases show different patterns, suggesting that the device can be advantageous toward expeditious diagnosis of cardiovascular and cardiac illnesses.
