Waseda University has developed a wireless circuit based on a new principle (parity time (PT) symmetric resonance coupling circuit (parallel connection)) and confirmed that the sensor sensitivity is improved by 2000 times.
Since this system is effective by installing a negative resistance on the detector side, the conventional sensor circuit can be used as it is. This system enables wireless measurement of sugar content in tears, which has been difficult to measure in the past. It is possible to numerically evaluate healthy people and diabetic patients, and contribute to the treatment and prevention of diabetic retinopathy, which is the leading cause of blindness in the world.
Furthermore, since blood lactic acid can be measured through the skin, it is expected to be applied to the monitoring of sepsis, for which the fatality rate increases at 2.0 mM or more.
