IIT Jodhpur fabricates a highly sensitive device for lead detection

Researchers at IIT Jodhpur have fabricated a portable sensor for detecting lead in water. It can detect lead even when present at extremely low concentration of 0.018 ppb, much lower than the WHO limit of 5 ppb for drinking water. A highly sensitive, portable device that can detect the presence of lead in water even … Continue reading IIT Jodhpur fabricates a highly sensitive device for lead detection

IIT Bombay’s sensor detects zinc in sweat, soil

IIT Bombay researchers have fabricated a sensor that can detect zinc over a wide concentration range — 0.1-500 ppm. The electrochemical sensor can be used for detecting zinc in the soil even in the presence of other elements and also at minute levels as seen in human sweat. A highly sensitive sensor that can detect … Continue reading IIT Bombay’s sensor detects zinc in sweat, soil

IIT Jodhpur fabricates a highly sensitive hydrogen sensor

A research team from IIT Jodhpur and IIT Hyderabad have together fabricated a sensor that can detect hydrogen gas even when present at extremely low concentration of 1 ppm. The sensitivity is 30% at 1 ppm hydrogen concentration and 74% at 100 ppm concentration. A sensor that can detect hydrogen gas even when present at … Continue reading IIT Jodhpur fabricates a highly sensitive hydrogen sensor

IIT Madras develops breath humidity sensor for wearable electronics

IIT Madras researchers have fabricated a sensor that can measure minute variations in relative humidity levels in the exhaled breath. It can detect ethanol and acetone in the oral breath of alcoholics and diabetics, respectively. The highly sensitive sensors can be integrated into wearable electronics. A nanofibre sensor capable of sensing minute variations in relative humidity … Continue reading IIT Madras develops breath humidity sensor for wearable electronics

IIT Bombay makes low cost vibration sensors

Researchers at IIT Bombay have made low cost, piezo-resistive vibration sensors that can be used for monitoring the health of industrial machines and equipments and help identify incipient failures. This enables efficient maintenance schedule planning. The sensors were validated by using portable Bluetooth speakers. Acoustic recordings for different machine operating conditions were played on the speaker and … Continue reading IIT Bombay makes low cost vibration sensors
