IMB-CNM in the GSMA Mobile World Congress
A real-time sweat sensor is presented, which can be integrated in smartwatches, patches or wearables.
The IMB-CNM sensor is a low-cost system that can measure pH, glucose, lactate and the electrolytes (sodium, potassium calcium and chlorine) of sweat. These parameter provide useful information for sport training programs and to detect alarm situations (such as dehydration or exhaustion). The system is based on a microfluidic structure made on paper that takes the sweat and transports it to silicon microsensors. The device is presented at the GSMA Mobile World Congress, held in Barcelona from 27 February to 2 March. IMB-CNM is also showing an ISFET (ion-sensitive field-effect transistor) sensor for the measurement of pH and ions, similar to a strip sensor. It can be applied in health, environment and food industry. The development of both technologies has been leaded by Antoni Baldi.
