The last ten years have witnessed a renewed interest in cellulose research and application, sparked mostly by technological interests in renewable raw materials and more environmentally friendly and sustainable resources. We have come across that cellulose based paper can produce a bending displacem...
Invoking piezoelectricity of regenerated cellulose, Piezo Paper can be made from the cellulose EAPap by maximizing its piezoelectricity and eliminating ions in the cellulose EAPap. Piezoelectric charge constant, d31, of this Piezo Paper is in the range of 30-50 pC/N, which is comparable with known p...
Cellulose based EAPap has some challenges in terms of small deformation, sensitiveness to humidity and loss of durability. To improve the deformation and durability, ion migration effect of cellulose EAPap has been maximized by incorporating PEO/PEG, chitosan, sodium alginate, conducting polymers, i...
Renewability and biodegradability of cellulose are really essential behaviors for state-of-the-art applications because these eco-friendly behaviors can make devices disposable. On the other hand, inorganic functional materials such as carbon nanotubes, titanium dioxide (TiO2), tin dioxide have supe...
Owing to its abundance, biodegradability and specific properties, cellulose is a very important renewable resource for the development of environmentally friendly, biocompatible and functional materials. Zinc oxide (ZnO) is a wide band gap semiconductor having a high electron-hole binding energy and...
Remote power transmission is very challenging in many areas such as space applications, information technology devices, smart sensor units for remote sensing, smart actuators, micro-aerial vehicles (MAV), flying robots, and space vehicles applications which require autonomous operations. On the cont...
EAPap material is attractive for developing biomimetic actuators, flying magic papers and biodegradable MEMS sensors. However, there are challenges of developing thin-film electrodes and flexible electronics on EAPap materials. We have successfully developed soft lithography technologies such as lif...
Electro-Active Polymers (EAPs), also termed artificial muscles due to their operational similarity to biological muscles, refer to a class of materials that has received much attention in the last ten years, owing to the unique set of promising characteristics such large strains in response to an el...
