Student develops breath-sensor device to let the disabled communicate

There isn’t a dearth of products developed to help disabled wheelchair users. But not all are as applicable and innovative as the breath-sensor apparatus created by 17-year–old Susant Pattnaik of Orissa, India. This device is created for those who use wheelchairs, to assist them with their normal chores just by breathing into this sensor-equipped device. Comprising four components: sensor, controller, transmitter and a receiver, the breath sensor and remote control device was created in two years with an investment of Rs 2-3 lakh.

Pattnaik’s breath sensor is a battery-powered device, which uses wireless signals to communicate with the wheelchair – this by converting breath into electromagnetic energy. According to Pattnaik, the prototype device has bright prospects and many applications, which besides allowing the individual to steer the wheelchair can also let the user signal food, water, washroom and even turn on/off an electric switch – this by the breathing alone. Pattnaik says the breath-sensor technology can even be implemented in a tractor, which could allow a paralyzed person run a tractor on a field by breathing alone. National Innovation Foundation (NIF) has begun value additions to the prototype to get it to the product stage.
