Summary
IISER Bhopal: The device developed from this material has a higher sensitivity to pressure than existing materials, indicating it is a promising future development of pressure sensor technology.
Expansion
IISER Bhopal: Researchers at the Indian Institute of Science Education and Research (IISER) Bhopal have successfully developed a new, flexible organic crystal. These crystalline materials have great potential in highly sensitive pressure sensors. The understanding of the response of these crystals to mechanical deformation was made in collaboration with researchers from the University of Queensland and the Queensland University of Technology. According to the information, the device developed from this material has a higher sensitivity to pressure than existing materials, which represents it as a promising future development of pressure sensor technology.
A new level of design freedom
As far as the use of organic materials is concerned, there is a growing interest in electronic applications. These organic materials are flexible which makes them suitable for making flexible electronic devices such as displays and sensors that can be bent or curved and provide a new level of design freedom. Due to the low number of defects and minimum limitations, organic crystals have immense future potential, especially in the field of electronics.
The use of new organic crystals flexible enough
Researchers from IISER Bhopal, as well as the University of Queensland, have jointly created a new organic crystal named 4-trifluoromethyl phenyl isothiocyanate (4CFNCS) which is flexible enough. Talking about the research, Professor Deepak Chopra, Department of Chemistry, IISER Bhopal, said that they have carried out an in-depth analysis using experimental techniques such as synchrotron microfocus X-ray diffraction measurements to understand the flexibility level of 4CFNCS.
Very useful in the design of electronic components
This showed that the arrangement of the atoms allows them to bend and stretch without breaking when subjected to mechanical stress. The sliding of molecules in many directions provides complex helical motion in the crystal. The team combined 4CFNCS with an electrically conductive polymer, PEDOT: PSS, to make the piezo-resistive sensor. Dr. Mitradeep Bhattacharjee, assistant professor of electrical engineering and computer science, pointed out that apart from applications for touch screens, such materials would be very useful in the design of flexible electronic devices, for example, wearable devices and self-powered devices that may be used in healthcare, intelligent systems. are used in.
