Aiming to lend support to geriatric care by aiding caregivers to reach out to the aged on time, students of the Indian Institute of Technology (IIT) Kharagpur have developed two interconnected android smartphone applications, an official said on Monday.

The app named ‘CARE4U’, developed by an interdisciplinry team of 2nd year B.Tech students, connects the caregiver to the elderly. While one of these apps can be installed on the phones of the elderly, the other can be attached to the smartphone of the caregiver.

“The neural network-based fall detection algorithm in the app installed on the phone of the elderly can detect whether the elderly has fallen down. If there is a fall, it automatically calls the caregiver and emergency services with the location of the elderly person,” a statement said.

The other features include detecting emotion by taking a picture and calculating the mood index. To make this feature more effective the team has developed a cognitive intelligent chatbot for the elderly person to engage with.

“We customized it to recognize the current mood of the person and, accordingly, fine-tune its conversations with that of the person. For example, the chatbot can recommend a motivational quote or an old song when the person is sad,” said team member Kanishka Haldar from the Department of Electronics and Electrical Communication Engineering.

Moreover, the app can also do other activities like make a call, send a text, book a cab and so on. It also has a record of medical histories, an account of allergies, an SOS button, real-time location tracking, among others.

The ‘CARE4U’ app includes a ‘Medicine Reminder’ feature to remind both the elderly person as well as the caregiver that it is time for the former to take medicine.

 Indian Institute of Technology Mandi researchers in Himachal Pradesh are developing thermoelectric materials that can efficiently convert heat into electricity.

While solar power has received a lot of attention, other alternative sources, even if less known, are equally promising.

Generating power from heat, for example, is attractive as there is a lot of energy that is generated through human activity in industries like power plants, home appliances and automobiles, where most of this heat is lost.

A research team led by Ajay Soni, Associate Professor (Physics) with the School of Basic Sciences, IIT-Mandi, is studying materials that can convert heat into electricity.

The team has been engaged in research on thermoelectric materials and many of its papers have been published in reputed peer-review international journals, including Applied Physics Letters, Physical Review B and Journal of Alloys and Compounds.

“Thermoelectric materials work on the principle of Seebeck effect, in which electricity is generated due to temperature differences across the junction of two materials,” Soni said.

A typical thermoelectric material must have the trifecta properties of high thermoelectric power and electrical conductivity, and low thermal conductivity with a capability of maintaining a temperature gradient.

This combination of properties, Soni said, is hard to come by and a few semiconducting materials must be tweaked further for good thermoelectric efficiency.

In the Western world, many automobile companies, including Volkswagen, Volvo, Ford and BMW, are developing thermoelectric waste heat recovery systems that promise three to five per cent improvement in fuel economy.

Other potential applications of thermoelectric energy harvesting include powering consumer devices and electronics, aviation, as well as space applications.

About 70 per cent of energy globally is wasted as heat and this heat is released into the environment, becoming one of the key drivers of global warming.

The trapping and conversion of waste heat into electricity can serve the dual purpose of energy self-sufficiency and environmental preservation. (IANS)
