As mobile electronics continue to evolve, the need for high-output, long-lasting rechargeable batteries has grown tremendously. Rechargeable lithium ion (Li-ion) batteries have high energy/weight ratios and high charge/discharge efficiencies relative to other rechargeable batteries which make them ideal for modern portable electronics, medical devices,...

Diffraction gratings are an important component in several applications including optical telecommunications and spectroscopy. Their usefulness increases if the gratings are externally tunable. To date, the basis for tunable gratings has been hard materials through multiple steps of micromachining technology. Another effort speaks of using the sinusoidal...

Recently, the discovery of flexible and stretchable electronics has brought about the potential for many new applications previously unattainable with rigid electronics. The lone inhibitor to the advancement of this technology is the lack of a formidable flexible and stretchable power source. Considering all possible power sources, supercapacitors...
