Non-contact Measurement Using Ultrasonic Technology for Human Anthropometric: A Narrative Review

Abstract

Introduction: Stunting is a public health priority in low- and middle-income countries. Thus, the validity and reliability of anthropometric measurement tools become critical for early stunting detection in children.  Objective: This article aims to review the use of ultrasonic sensors in human anthropometric and body measurements. Methods: We conducted a narrative review of articles regarding the ultrasonic sensor for measuring anthropometrics in the human body between 2016 and 2022. We focused particularly on the use of ultrasonic sensors in children’s anthropometrics, body size, and body measurements. Results: According to the findings, the majority of non-contact measurements using ultrasonic sensors were applied to adults, though several studies also involved pregnant women to measure foetus size. These studies showed that ultrasonic sensors were beneficial as they served as accurate, reproducible, affordable, and easy-to-use tools. Conclusion: Future studies are warranted to understand the significance of the non-contact measurements for children’s anthropometrics, especially for early stunting detection.
