In the 8th edition of the Indian Institute of Technology Delhis upcoming event Open House students and faculty members presented their innovative and commercially viable research projects. This Saturday,IIT-Delhi will open its gates to schools,colleges and the public to have a look at these projects. RESPONSIVE CAMOUFLAGE TECHNIQUE Developed by Muksit Ahamed Chaudhury,BS Butola and Mangala Joshi at the Department of Textile Technology,the project deals with the development of responsive camouflage using thermochromic colorants. Plain woven cotton fabrics that are electrically conductive are used for the purpose. Although thermochromic colorants have been used for camouflage techniques before,under normal conditions,the colour depends upon surrounding temperature, said Muksit,an MSc student at IIT-Delhi. The novelty of this project is that it allows the user to control the colour camouflage,irrespective of his surroundings,in less than 30 seconds. When an electric current passes through the fabric,heat is generated and the temperature of the fabric rises,irrespective of the surrounding temperature,adjusting its colour. TISSUE ENGINEERED INTER-VERTEBRAL DISC A biometric artificial disc has been made using silk fibres and cells from the patients body since both contain amino acids in their composition. The project has been developed by Maumita Bhattacharjee and Dr Sourabh Ghosh at the Department of Textile Technology. Precise fiber alignment guides the cells to follow the same orientation and eventually ensure that the overall biochemical functions of the tissue, Dr Sourabh said. INDOOR NAVAGATION SySTEM FOR VISUALLY CHALLENGED Roshni is an affordable cell-phone based indoor navigation system for the visually challenged. Developed by Dhruv Jain and Prabhav Agrawal,the system helps visually challenged persons navigate independently in a building. The idea was to challenge the constraints of independent mobility and navigation in an unfamiliar indoor environment, Dhruv said. The device,according to the developers,is easy to use,costs little and can be attached to the users waist or walking cane. INTERACTIVE VISUAL DISPLAY The project takes touch-screen technology a step further with their multiple user interface. The display provides multi-dimensional imagery and multi-touch interaction visual display. Unlike the iPad and other touch-enabled devices,this one can be used by multiple users at the same time, said Manisha Bhardwaj from the Electrical Engineering Department. The device provides a 180/270/360 degree viewing without wearing any glasses.
