IISc researchers have successfully found a way to navigate tiny, geometrically identical filaments, and subsequently place them at predefined positions with respect to each other. The method works without any physical contact with the filaments, and this can have important applications in nanomedicine.

Under Prime Minister Narendra Modi, a flagship campaign of the government, “Make In India” was launched on September 25, 2014, with a mandate to ‘put India on the world map as a manufacturing hub’. Covering 25 industry sectors, Make in India is seen as a global call for companies to manufacture in India. The action plan includes interfacing with global investors, grievance redressal through dedicated business facilitation channels and resolve policy issues in ease of doing business in India.
Miniaturisation of VLSI (Very Large Scale Integration) devices has allowed for their usage in versatile applications such as baby monitors and heart rate monitors. One drawback to such miniaturisation of integrated circuits is the reduced capacity and lack of accessibility of the batteries used as power sources. This requires that the power consumed by the device be reduced as much as possible. To address this problem, Sagar Gubbi and Bharadwaj Amrutur of the department of Electrical and Communication Engineering at Indian Institute of Science (IISc) have developed a novel method which manages power better. The new method more efficient, reliable, and produces a hundred-fold improvement for certain operating conditions.
The current age is called the “Information Age”. People want “information” on their fingertips. Information here may mean a variety of things: mails and messages, news, financial transactions, railway bookings and more. Some people may also need more specialized or personalized forms of information. However, in a developing country like India, not everyone can afford a personal computer with internet access. On the other hand, India has also seen a remarkable proliferation of mobile phones across much of the society, and across most age groups. The new generation of such phones, called smartphones, not only provide regular internet access, but also a platform for users to create new programs (popularly called “App”s) for specialized and personalized services. Dr. Aditya Kanade, Scientist and Assistant Professor of Computer Science in Indian Institute of Science (IISc), Bangalore is working on the design and implementation issues of smartphone apps. In his words, the widespread adoption of smartphones is a step at democratizing information access.
Anyone who has stepped into the IISc campus is aware of its enormous expanse that is comparable to the area of a small city; however, it is not quite as simple to judge the scope of scientific work done at this institute. It is the uniqueness of each laboratory that makes the work done at IISc so valuable. Some researchers here work on things as large as satellites and ships while others work with the thinnest known material, called graphene. The Nano-micro Systems Laboratory, headed by Assistant Professor Dr. Abha Misra, is busy with cutting-edge research involving materials which are classified into the lowest physical size scale.
Researchers at the Indian Institute of Science, Bangalore have now devised a technology which can efficiently extract energy from vibrations that are almost always present around us. Though not from thin air, this development has a wide scope of applications and could power smalls LED lights, fire and smoke alarms, biomedical devices to name a few.
Gold nanoparticles coated with a thin layer of platinum may make hydrogen fuel cells more efficient, finds an IISc study. Such small spikes in efficiencies take us closer to affordable hydrogen fuel, which is considered as a cleaner replacement to conventional fuels.
A heart beat generates pressure wave which propagate throughout the arterial system. The shapes of wrist pulse waveforms are influenced by their continuous interaction with the non-uniform arterial system. These waves expand the arterial walls as they travel along and the expansions are palpable as the wrist pulse. A typical pulse signal has a multi period trend. Systolic wave with higher amplitude contributes to the main component of the pulse signal. The diastolic wave contributes to the lower amplitude secondary wave of the pulse signal. The information regarding heart is contained in the systolic wave whereas the secondary wave provides information on the reflection sites and the periphery of the arterial system. Analyzing this information would help one detect abnormalities in the body condition. Many efforts have been made recently to analyze wrist pulse pressure signals using efficient computer based techniques
When you combine unbridled passion for Indic languages and the drive to give back to the nation that nurtures, we get researchers like Shiva Kumar H R. His work titled ‘Gift of New Abilities’ won him the ‘Gandhian Young Technological Innovation Award-2015’. Shiva Kumar and Prof. A G Ramakrishnan have developed high accuracy Optical Character Recognizers (OCR) for Kannada and Tamil languages that convert scanned pages of a printed document/book into e-text.
Shiva Kumar and Prof. A G Ramakrishnan have developed high accuracy Optical Character Recognizers (OCR) for Kannada and Tamil languages that convert scanned pages of a printed document/book into e-text. In addition, they have developed an intuitive GUI called Print-to-Braille tool that enables even non-technical people to quickly use their OCR and make corrections to the mistakes, if any, in the text output by the OCR. By using their OCR along with the Print to Braille tool, the family members or friends of visually challenged people are able to scan any printed book/document and convert it into Unicode text within a short span of time. The visually challenged person can listen to that e-text through any Text to speech (TTS) synthesis software. The e-text can also be converted into Braille codes and printed using a Braille embosser.
