Recently, engineers at Rutgers University’s New Brunswick campus have created a new fitness tracker that wirelessly connects to smart phones and will bring a new wave of personal health and environmental monitoring equipment.
It contains a biosensor that can calculate particles, including blood cells, bacteria, and organic or inorganic particles in the air.
This plastic fitness tracker includes a flexible circuit board and a biosensor. Biosensors contain a channel or tube that is thinner than human hair and has gold electrodes embedded inside it. The bracelet contains a circuit for processing electrical signals, a microprocessor for digitizing data, and a Bluetooth module for wirelessly transmitting data.
The blood sample is obtained by acupuncture, and the blood flows in through the channel, and the number of blood cells is recorded. The data is then sent wirelessly to an Android smartphone’s app (app), which can process and display the data. This technology is also compatible with iPhones and other smart phones.
In the wild, in the office, and in hospitals, medical professionals can quickly obtain blood test results from patients without the need for expensive and cumbersome laboratory equipment. The counting of blood cells can be used to diagnose diseases, such as low red blood cell counts, and can be used as a marker for conditions such as internal bleeding.
Mehdi Javanmard, assistant professor of engineering at the campus, said: “For a range of diseases, blood counts are very important. High and low white blood cell counts can be a hallmark of specific cancers such as leukemia.”
