Purpose

Dehydration is a severe condition that the elderly people, persons with disabilities, or patients in hospitals are apt to cause. Our purpose is to develop a simple blood osmotic pressure sensor that requires only a small amount of blood.

Achievement

We have developed several elemental technologies for the sensor, such as a blood cell adsorption filter that does not require a pump mechanism.
