Anjali, who has made several such tools, told IANS one to five emergency panic buttons could be added to it. "It operates in a 100-metre range and is too tiny to be noticed. Its battery last nearly 8 months. Women can keep the button that costs Rs 2,500 anywhere in the house as per their convenience," she said.

It also has an audio-recording option, which could later serve as evidence. It could be used by housewives and girls living in paying guest (PG) accommodations.

"This type of innovative devices helps prevent crime against women," said Gorakhpur scientific officer Mahadev Pandey.

"Anjali has made many such devices in the past, including anti-rape jeans and shocking gloves. This device is very important for the safety of women. It will prove to be very effective, especially in the coronavirus time," said Shyam Cherasia, research and development in-charge of Ashoka Institute of Technology and Management.
