Engineers from the Indian Institute of Science have developed a system through which doctors can monitor the core body temperature of the newborns, on their mobile phones. This will go a long way in managing health complications arising out of a small dip in body temperature of the newborns.

Researchers from the Indian Institute of Science (IISc) have developed a novel algorithm that can analyse traffic movement and aid in detection of unusual vehicular behaviour.
“We’re aiming to develop an algorithm to identify dominant flow paths along different directions and using these paths to detect any anomalies such as a vehicle moving beyond the speed limit or travelling along an unusual path”, says Srinivas, a member of the team that developed the new method.
Video cameras have long been used for surveillance of myriads of activities, from crowd behaviour analysis to traffic monitoring. Conventionally, such activities were analysed or monitored by human personnel. In recent years, thanks to proliferation of surveillance cameras, we are dumped with so much of data that it has become too expensive to analyse them through traditional methods. Hence, computerised techniques are being developed to assist security personnel in analysing such videos.
Engineers from the Indian Institute of Science have developed an endoscopy simulator that simulates the effect of physical contact. In the long run, this technology can be made economical and can be used to train endoscopists by providing them an immersive training environment.
Researchers at the Indian Institute of Science (IISc) have designed a new type of energy harvester that can scavenge electrical energy from weak vibrations. Vibration drives a liquid droplet and the motion of the liquid droplet produces electrical energy which can power portable electronic devices efficiently.
Conventional sources of energy are precious and they are getting exhausted at a very rapid pace. Scientists are looking for alternative sources of energy, like solar energy, wind energy, energy from bio waste etc., to replace the conventional sources. “Energy harvesting” is the conversion of unusual forms of energy, like heat, wind, vibration etc., which are otherwise wasted, into some usable form of energy. Efficient energy harvesting is the key to addressing our ever-increasing energy problem.
A recent study by Sourav Biswas, Goutam Prasanna Kar, and Suryasarathi Bose, from the Department of Materials Engineering at Indian Institute of Science (IISc) Bangalore has taken a step toward seeking the perfect shielding material. They have created a new material that has exceptional electromagnetic wave absorption capabilities in the microwave frequency, the frequency most often used by point-to-point communication devices.
A group of researchers at IISc have managed to "teach" the brain cells taken from a rat and cultured on a glass plate, to help navigate a robot through an arena—while avoiding obstacles.
The researchers took the brain cells of a rat, and allowed them to grow on a specialized tiny glass plate covered with multiple electrodes. They flooded it with a special liquid medium to keep it alive. In a few weeks, the cells grow specialised structures called dendrites, which connect to other cells, thus forming a network. This network starts showing spontaneous electrical activity with generation and transmission of tiny voltage spikes – much like within the brain.
A study in Indian Institute of Science has yielded an algorithm that can allow companies to advertize their products, or political parties to campaign over social networks within a fixed budget. The algorithm ensures that the campaign reaches maximum people, through an optimal combination of mass media broadcasts and providing incentives to people having good social contact.
Social media has become part and parcel of life over the last decade. Most of us use it not only as a tool to get in touch with friends, relatives and colleagues, but also as a source of information. It is not surprising that companies are increasingly taking to social media to advertise their products; recently, politicians have been using it for election campaigns.
Protecting organic devices against water vapour is a concern for many scientists. Organic devices are known to be highly reactive to atmospheric water vapour, a significant cause for their premature degradation. A successful solution was generated by a team of four researchers at the Department of Chemical Engineering in IISc. Using a polymeric nanocomposite, they have devised an efficient and economical barrier to protect organic devices.
Researchers from the IISc have developed new equipment that can ensure better safety of the digital telecom exchanges against lightning surges. The study is carried out by the researchers from the Department of Electrical Engineering, Indian Institute of Science, Bangalore.
