Abstract: The present invention relates to an ear-wearable device (100) comprising: a plurality of neuro-buds (100a), each neuro-bud (100a) comprising: a housing (102), a hub (104) disposed in the housing (102), a plurality of springs (2, 2a-2h) disposed on the hub (104), and a biosensor electrode (1, 1a-1h) disposed on each spring (2, 2a-2h) and adapted to be in contact with an ear canal for detecting at least one physiological parameter of a user, wherein the plurality of springs (2, 2a-2h) are adapted to expand for extending the biosensor electrode (1, 1a-1h) to establish contact with the ear canal and to contract for retracting the biosensor electrode (1, 1a-1h) to break the contact; and a controller (100, 300) in communication with the biosensor electrode (1, 1a-1h) and adapted to: receive at least one value of the at least one physiological parameter detected by the biosensor electrode (1, 1a-1h), and generate health insights of the user based on the at least one physiological parameter.
