In this paper, we report a study on the infrared stealth properties of cotton fabrics with ZnO: (Al,In) coating. Al, In doped ZnO samples were prepared through sol-gel method. The crystalline phase of the ZnO: (Al, In) solids were determined by XRD. IR-2 Dual-Band Infrared Emissivity Measuring Instrument was used to test the infrared emissivity of the coated fabric. Infrared stealth effect of ZnO: (Al, In) coated fabric was measured using thermal infrared photospectrometry instrument. It was found that the ZnO: (Al, In) thin film has a low infrared emission in the range of 8 ~ 14μm wavelengths, and the addition of Al and In leaded to a better infrared stealth effect.

In recent years, VO2 has emerged as a popular candidate among the scientific community across the globe owing to its unique technological and fundamental aspects. VO2 can exist in several polymorphs (such as: A, B, C, D, M1, M2, M3, P, R and T) which offer a broad spectrum of functionalities suitable for numerous potential applications likewise smart windows, switching devices, memory materials, battery materials and so on. Each phase of VO2 has specific physical and chemical properties. The device realization based on specific functionality call for stabilization of good quality single phase VO2 thin films of desired polymorphs. Hence, the control on the growth of different VO2 polymorphs in thin film form is very crucial. Different polymorphs of VO2 can be stabilized by selecting the growth route, growth parameters and type of substrate etc. In this chapter, we present an overview of stabilization of the different phases of VO2 in the thin film form and the identification of these phases mainly by X-ray diffraction and Raman spectroscopy techniques.

This chapter reports a hybrid wearable energy harvesting system. Integration of microwave antenna on thin film amorphous silicon solar cell creates a hybrid system that can harvest both the solar and microwave energies. The antenna designed on solar cell will harvest the microwave energy at dual frequencies 1.85 GHz and 2.45 GHz with an effective return loss of 28dB and 27dB respectively. A complete hybrid harvesting system consist of a flexible solar cell, antenna, voltage doubler, and impedance matching dual band filter. The rectifier, designed on a rigid glass-reinforced epoxy substrate, is a voltage doubler and a matching circuit is designed by microstrip lines is used.
