April 9, 2021 4:26 pm US research company Tiger Tech Solutions has designed a wearable sensor that hopes to stop the spread of Covid-19 by improving the ability to identify cases in asymptomatic individuals. The Covid Plus monitor has recently been authorised for emergency use by the Food and Drug Administration (FDA), the organisation that ensures the safety and efficacy of medical devices and health products in the US. The armband device is the first machine learning-based Covid screening product to be granted such authorisation. It’s intended for use by trained personnel on individuals over the age of five. It works by identifying biomarkers – a measurable indicator of a disease state – that could indicate the presence of the virus, such as hypercoagulable conditions (like sepsis or cancer) or hyper-inflammatory states (like allergic reactions).
