In the science fiction movie "Fantastic Voyage" released in 1966, treatment from inside the human body by miniaturized men in a miniaturized submarine injected into a blood vessel is depicted. Although such a fantastic scenario is unlikely, precision examination and treatment can be performed by extremely small medical devices which have several functions.

New minimally invasive medicine and health care devices realized by micro machines
Using microfabrication technologies including MEMS (Micro Electro Mechanical Systems) technologies novel and useful medical devices and health care devices can be realized with high-performance multi-functionalized systems including micro sensors, micro actuators and integrated circuits. More accurate diagnosis and safe therapy without large incisions and physical burden on the patient can be performed using the small high-performance multi-functionalized medical tools, for example endoscopes and catheters. Advanced diagnosis and therapy will be also realized using new high-performance multi-functionalized medical tools. Thin, soft and small wearable health care devices which is mounted on human body surface enable new useful measurement item in daily life, for example blood lactate, blood glucose and stress level. Basic fabrication technologies and fabrication processes required to realize these devices mentioned above have been also developed. Not only fabrication but also several evaluation and verification experiments are also performed with medical doctors and medical device manufacturers.

Research at universities only for the sake of research is no longer acceptable, and thus we aim to apply our efforts to the realization of practical medical devices. We are therefore actively cooperating with clinicians and medical equipment companies under the auspices of Tohoku University Biomedical Engineering Research Organization and a venture company established for the above-mentioned purpose.
