Micro-total analysis systems (microTAS) are expected to be useful in daily healthcare applications in the near future because of their ability to measure biological information from molecules in the human body. This information is now assessed using sophisticated analytical systems at specialized institutes. MicroTAS is based on microfluidics, a multidisciplinary field that involves precise control of fluids at the sub-millimeter scale. A microfluidic device handles liquid just as an electronic device handles electricity. In this article, we introduce microTAS technology currently under development that makes measurement protocols as simple as possible through the use of microfluidics and enables end users to measure their health condition by themselves.

NTT has developed a conductive fabric called hitoe that enables continuous measurement of the biological signals of the person wearing it. Heartbeat variations and electrocardiogram signals detected through hitoe are transmitted wirelessly by a compact dedicated device to a smartphone or tablet, where they can be readily checked using an application. Such technology is expected to lead to the creation of new services in fields such as sports training, health enhancement, security and safety, medical care support, and entertainment. In this article, we introduce some examples of approaches to application development.

The flow of blood that circulates through the entire human body and supports life changes dynamically with our emotional and physical state and reveals a huge amount of information. If the flow of blood could be easily visualized in our daily lives, we could expect to see a range of useful applications in areas such as health, beauty, and sports. In this article, we introduce an ultracompact, wearable blood flow sensor that is linked to a smartphone, making it possible to view the flow of blood anywhere and at any time.
