Sustainable Triboelectric Sensors

Contact electrification is a natural phenomenon that occurs in our environment. This phenomenon usually seems as a negative effect for electronic devices, cars, planes and etc., and so it is considered an undesirable, a dangerous situation in many technologies because of high voltage static electiricity discharge. It has been shown that charging-discharging process of electrostatic charges can occur and be utilized as a sensor which made of two insulators having differences in hypothetical energy level of electrons. All kinds of available mechanical energy and environment temperature but wasted in our daily life such as human motion, vibration on bridge, ambient and atmospheric temperature, rotating tire, wind, flowingwater, and more can be harvested and detected by using this organic TES system. The detecting motion process arising from vibrations using the voltage and current output signals of the TES will be useful as a self-powered sensor with potential applications for touch pad and smart skin technologies.

Self-Assembled Colloidal Plasmonic Crystals

Plasmonic colloidal crystals offer unprecedented opportunities for the realization of all-optical integrated circuits and high-speed optical computing. We have recently developed a simple spin-coating technique that combines the simplicity and cost benefits of traditional self-assembly with the scalability and compatibility of nanolithography in creating wafer-scale colloidal photonic crystals with nonclose-packed structures. We currently focus on the fundamental understanding of the shear-induced ordering mechanisms during spin-coating and the photonic band gap properties of self-assembled photonic crystals.

Templated Plasmonic Nanostructures

Surface plasmon-based plasmonics provide another powerful tool for confining, channeling, and amplifying light on the subwavelength scale, enabling highly complex nanooptical circuits. We are investigating the plasmonic properties of templated metallic nanostructures, including surface plasmon spectroscopy through metallic nanoarrays and surface-enhanced Raman scattering (SERS) at nanostructured metallic surfaces. We are also developing new plasmonic nanostructures for targeted drug delivery and hypothermal treatment of cancers. Furthermore, multifunctional nanostructures are being explored for developing efficient OLEDs by combining the directional inhibition and redistribution of light in photonic band gaps with surface-plasmon-enhanced emission.
