Abstract: Embodiments herein relate to car-wearable devices and systems that can analyze a device wearer's gait and/or provide gait training. In a first aspect, an car-wearable device is included having a control circuit, a motion sensor in electrical communication with the control circuit, a microphone in electrical communication with the control circuit, and an electroacoustic transducer in electrical communication with the control circuit, wherein the car-wearable device is configured to calculate one or more desired gait parameters, and provide a series of audio cues to a device wearer consistent with the one or more desired gait parameters.

Abstract: Embodiments herein relate to ear-wearable stress and anxiety monitoring systems, devices and methods. Embodiments herein further relate to ear-wearable systems and devices that can detect and take actions to alleviate device wearer's stress and anxiety. In an embodiment an ear-wearable stress and/or anxiety monitoring system is included having a control circuit, a microphone, and a sensor package that can include a motion sensor. The ear-wearable system is configured to evaluate data from at least one of the microphone and the sensor package and classify a stress level of a device wearer using a machine learning classification model and periodically update the machine learning classification model based on indicators of stress experienced by the device wearer.

Abstract: Embodiments herein relate to ear-wearable systems and devices that can detect respiratory conditions and related parameters. In an embodiment, an ear-wearable device for respiratory monitoring is included having a control circuit, a microphone, and a sensor package. The ear-wearable device can be configured to analyze signals from the microphone and/or the sensor package and detect a respiratory condition and/or parameter based on analysis of the signals. In an embodiment, an ear-wearable system for respiratory monitoring is included having an accessory device and an ear-wearable device. In an embodiment, a method of detecting respiratory conditions and/or parameters with an ear-wearable device system is included. Other embodiments are also included herein.

Abstract: Embodiments herein relate to ear-wearable devices and systems that can detect a risk of infection in a device wearer. In a first aspect, an ear-wearable infection sensor device is included having a control circuit, a microphone, a sensor package, and an electroacoustic transducer, wherein the electroacoustic transducer is in electrical communication with the control circuit. The ear-wearable infection sensor device can be configured to analyze data from the sensor package to determine physiological parameters of a device wearer and evaluate the physiological parameters to detect the risk of an infection. Other embodiments are also included herein.
