A wearable multi-sensor device for measuring physiological properties includes a plurality of non-invasive sensors, such as a single-sided electrocardiography sensor, a bioimpedance and electrodermal activity sensor, a skin temperature sensor, and a photoplethysmography sensor. The device is configured to secure a skin-facing side of the sensors to exposed skin of a user and includes a communication module configured to receive signals from the plurality of non-invasive sensors and output data from the device, the being suitable for use in predicting glycemic events in the user.
