Investigation of continuous human weight monitoring based on optical fiber sensor

Measuring weight help to show the growth process for health monitoring. It is crucial to get an accurate value to determine the actual weight of human without any external load. The aim of measuring human weight is to access and monitor fluid nutrition status and monitor the effectiveness of nutriti...
