About
Light Touch Technology Inc. (LTT) is an Osaka-based health tech startup founded in July 2017 that is developing the world's first non-invasive blood glucose sensor that requires no blood sampling. Using high-brightness mid-infrared (MIR) laser technology, LTT's sensor measures blood glucose levels simply by touching a finger to the device, targeting diabetic patients who must frequently monitor glucose levels. The company has received multiple awards including a CES 2022 Innovation Award and recognition from Japan's Ministry of Internal Affairs and Communications. LTT raised approximately ¥500 million ($3M) and has attracted investment from TAMRON, and is backed by grants from the Mitsubishi UFJ Technology Development Foundation.
