Manisha Mohan is an aeronautical engineering student at SRM University in the Indian city of Chennai.
She is also a young woman in a country that was thrown into chaos following the brutal gang rape of a 23-year-old student in Delhi in December, 2012.
Together with fellow students Niladhri Basu Bal and Rimpi Tripathi, she decided to use her technical skills to try and do something to help protect women like her.
The bra is fitted with a pressure sensor connected to an electric circuit.
“Firstly, the system is placed in a bi-layer fabric, which ensures insulation to the victim,” says Ms. Mohan.
“Also the pressure values for squeeze, pinch and grab have been calibrated. The force applied on hugging does not satisfy the conditions for actuation of the device, and there is also a self-actuation switch where a woman can actuate it by herself when in unsafe environment.”
