    Abstract: A hearing aid includes a speaker driver, an optical source secured directly to the speaker driver, an optical detector secured directly to the speaker driver, a first light guide extending outwardly from the optical source and in optical communication with the optical source, and a second light guide extending outwardly from the optical detector and in optical communication with the optical detector. The first light guide is configured to deliver light from the optical source into an ear region of the subject via a distal end thereof, and the second light guide is configured to collect light from the ear region via a distal end thereof and deliver collected light to the optical detector. The hearing aid may include at least one signal processor configured to process signals produced by the optical detector, and at least one of the following: an accelerometer, a humidity sensor, an altimeter, a temperature sensor.

    Abstract: A monitoring device configured to be attached within a portion of an ear of a subject includes an elastomeric arm having opposite first and second end portions. A sensing element is located at the elastomeric arm second end portion and includes at least one energy emitter configured to direct energy at a target region of the ear and at least one detector configured to detect an energy response signal from the target region or a region adjacent the target region. The monitoring device is configured such that the elastomeric arm first end portion engages the ear at a first location within the ear and such that the elastomeric arm resiliently bends such that a surface of the sensing element is urged into contact with the ear at a second location within the ear.

    Abstract: A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to detect/measure physiological information from the subject, and a processor configured to process the physiological information to detect subject stress, and to determine an origin of the subject stress. The processor can determine the origin of the subject stress by increasing a sampling rate of the PPG sensor to collect higher acuity physiological information. The processor also can determine the origin of the subject stress by processing data from the PPG sensor to determine whether the subject is likely to have atrial fibrillation. In response to determining that the subject is likely to have atrial fibrillation, the processor can increase a frequency of pulsing of an optical emitter of the PPG sensor and/or increase a sampling rate of the PPG sensor to collect higher acuity data for diagnosing that atrial fibrillation is truly occurring.
