“…Sensors are widely used in medicine to monitor various indicators in the body. Many parameters are measured by such monitoring, from action potential in cranial nerves 1 to corneo‐retinal potential, 2 blood oxygen saturation, 3 or respiratory index, 4 which has contributed to disease treatment and advances in medical science. Particularly, blood pressure, 5 as well as pressure in the brain 6 and other organs, is an important indicator; many methods to measure pressure were developed because pressure monitoring is very helpful for the treatment of serious diseases such as end organ damage and traumatic brain damage due to hypertension 7–9 .…”

This paper addresses a pressure sensor for body pressure measurement. Many pressure sensors have been developed for disease treatment in the medical field. However, these sensors require inserting electronic components and other sensor elements via surgical operations, so the measurement physically burdens patients. Hence, we proposed a needle‐type pressure sensor using MEMS (Micro Electro Mechanical Systems) cantilever. The sensor has a needle part with a thin membrane on the tip and is filled with incompressible fluid inside. The fractional resistance of the built‐in piezoresistive cantilever varies according to the pressure change applied to the needle tip. We can measure body fluid pressure with minimal surgery by inserting a simple needle into the target organ. Because the fabricated sensor responded to pseudo‐body pressure changes, it was suggested that the fabricated needle‐type pressure sensor could detect pressure inside the body.
