No more finger pricks!

World’s first blood glucose sensor without needles


Diabetes is a disease that a patient cannot well control glucose (blood sugar) in the blood and is called “source of all diseases” as it can cause various complications such as cerebral infarction, dementia, neuropathy, etc.

To treat diabetes, it is essential to measure blood glucose level accurately.  However, in a conventional way, a patient needs to finger prick to take a blood sample multiple times a day; that involves a physical pain, mental stress and infection risk.

Light Touch Technology (LTT) has developed the world's first blood sampling-free (non-invasive) blood glucose sensor using advanced laser technology; as one of the first ventures of the National Institutes for Quantum and Radiological Science and Technology.

We aspire to commercialize this advanced technology as a home medical device and a wearable device by miniaturizing the sensor significantly with the support of the New Energy and Industrial Technology Development Organization (NEDO).
