As we age, various problems threaten us in turn or at the same time: obesity in childhood, diseases related to lifestyle choices in middle age, and the possibility of becoming bedridden in later years. "Ubiquitous Echo" is a new portable supersonic echo imaging equipment. It can be used to visualize key components of the body (muscles, bones, subcutaneous fat) and give fat and muscle measurements in health care or beauty facilities, or even at home. We hope that this technology will help to maintain our health and to prevent elderly people from being confined to their beds.
