Measuring heartbeat from 3 feet away – Electric potential sensors
Robert Prance’s team at University of Sussex in UK have discovered and created a unique electric potential sensor that is a perfect voltmeter and can measure a heart beat from nearly 3 feet away. It measures the spatial electrical potential or field. This has been difficult since the electrometers that measure voltage, electric charge or…

Electrochemical sensors
Electrochemical assays have typically suffered from poor sensitivity compared to optical technology. In addition, they sometimes have a large background signal which makes detection of analyte difficult. However, the ability to detect the analyte in turbid or complex signal is the holy grail that is usually very difficult with optical methods. Many laboratories have struggled…
