Wearable device for measuring bidirectional nostril airflow

Abstract

A wearable device 100 for being worn on a nose of a person, comprises a main body 10 comprising: a ring portion; a first sensor housing 21 fixed to a first end of the ring portion; a second sensor housing 22 fixed to a second end of the ring portion; a power supply unit configured to supply electrical power; a controller; and a communication unit configured to perform communication with an external device. The first sensor housing 21 and the second sensor housing 22 are configured to be coupled to the nose, wherein the first sensor housing 21 comprises a first airflow sensor unit, wherein the first airflow sensor unit is configured to measure an airflow out of a first nostril of the nose and measure an airflow into the first nostril of the nose. The controller is configured to control the communication unit to transmit the measured airflow out of the first nostril and the measured airflow into of the first nostril to the external device. The first airflow sensor unit may comprise two sensors which measure airflow in and out of the nostril respectively. Figure 1
