Biosensor technology for wearable devices to monitor health and environmental exposures
Engineers at Rutgers University have created a smart wristband to enable a wave of personal health and environmental monitoring devices. The smart wristband can connect to your smartphones wirelessly. The technology can be added to watches and other wearable devices to monitor heart rates and physical activity.
Smart wristband can evaluate blood test rapidly
In the field, offices and hospitals, health professionals can get rapid blood test results from patients without the need for expensive and bulky lab-based equipments. Blood cell counts can be used to diagnose illness like low red blood cell count. There is a whole range of diseases where abnormally high or low white blood cell counts are indicators of certain cancers like leukaemia.
These smart wristbands can be used in a variety of biomedical and environmental applications. Patients will be able to continuously monitor their health and send results to physicians remotely. Using this band, people can keep a check on air pollutants and can also measure the number of tiny particles or dust they’re exposed to day in and day out.
Wristband can count the particles
The device has a biosensor that can count particles including the number of blood cells, bacteria and organic or inorganic particles in the air.
It includes a circuit board and a biosensor with a channel that is thinner than the diameter of a human hair. The channel is embedded with gold electrodes from the inside. It has a circuit to process electrical signals, a micro-controller for digitising the data and a Bluetooth module to transmit the data wirelessly.
Blood samples are obtained through pinpricks with the blood-fed through the channel and the blood cells counted. The data are sent wirelessly to an Android smartphone with an app that processes and displays data. The technology can also work on iPhones or any other smartphone.
Moreover, the ability of a wearable device to monitor the counts of different cells in the bloodstream would take personal health monitoring to the next level.
