Electronics, sensors and energy storage devices are the new waves behind economic development, security and communication1. Engineering small sizes of electronic, sensors and energy storage devices is the hurdle limiting efficient, portable and vast applications of Nano-devices for economic, security and communication advancement2. Silicon the major material used in transistors has approached its limit to fabricated Nano-devices3. The discovery of free standing, one atomic layer thick and two-dimensional graphene sheets with high conductivity, inert, high specific surface area, stable and high tensile strength material in 2004 has shown capabilities to replaced silicon in electronics, sensors and energy storage devices4. Graphene and carbon nanotubes allotropes of carbon have gained momentum as the best materials for the advancement of electronics, sensors and energy storage sectors. Research has shown that 3D structuring of graphene and carbon nanotubes will expand their properties as well as applications. Unfortunately there is no technology to synthesize these materials in 3D and in bulk for applications in electronics, sensors and energy storage devices. Here, we present new technologies to synthesize new 3D materials of graphene, carbon nanotubes, manganese dioxide and tungsten trioxide. We also illustrate some of the possible applications of some of these materials in sensor and electrochromic devices.
