Provided according to embodiments of the invention are photoplethysmography probes designed for use on a user's nasal alar. Methods of using such photoplethysmography probes are also provided herein.

An physiological measurement device provides a device body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The device body is flexed so as to position the housing over a tissue site. The device body is unflexed so as to attach the housing to the tissue site and position the optical assembly to illuminate the tissue site. The optical assembly is configured to transmit optical radiation into tissue site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.

A system may include a device configured to be implanted within a recipient and that includes an integrated circuit. The integrated circuit may include a first node configured to provide a bandgap reference voltage and a second node configured to provide a CTAT voltage. The first node may be coupled to a first input of an ADC and the second node may be coupled to a second input of the ADC. The system may also include a processor communicatively coupled to an output of the ADC. The processor may be configured to determine, based on the output of the ADC, the CTAT voltage. The processor may be further configured to determine, based on the CTAT voltage, a temperature of the device.

Embodiments herein relate to medical device systems including ear-worn devices. In an embodiment, a medical device system includes an ear-worn device including a control circuit, a microphone in electrical communication with the control circuit, an electroacoustic transducer for generating sound in electrical communication with the control circuit, and a power supply circuit in electrical communication with the control circuit. The ear-worn device can be configured to received signals from a separate medical device and generate a notification using the received signals. Other embodiments are also included herein.

The invention relates to an electrode for detecting a bioelectrical signal, for example EEG, on a skin surface. The electrode comprises a coating comprising iridium oxide, where the coating has a nanostructured surface pattern providing for a capillary and hydrophilic effect when in use.

A method for generating an acoustic stimulus for use in an ear biometric process on a user, the method comprising: receiving an indication of stimulation frequencies for use in the ear biometric process; grouping the stimulation frequencies into bands of a psychoacoustic scale; generating the acoustic stimulus, the acoustic stimulus comprising a masked bandpass component within each band of the psychoacoustic scale that comprises one or more of the stimulation frequencies.

Disclosed is a method, a headset and a system for determining heart rate data of a user. The system comprising a headset for voice communication, the headset being configured to be worn at least partly at or in the ear of the user, the headset comprising: a voice communication unit for enabling a voice communication call mode for establishing a call between the headset and a far-end device; a speaker for reproduction of audio signals; a microphone for reception of audio signals; a photoplethysmograph (PPG) sensor for optically measuring through the skin of the user in or at the ear of the user; wherein the system comprises a processing unit connected to the PPG sensor, where the processing unit is configured for determining heart rate data of the user based on the PPG sensor measurements; wherein the system comprises detecting whether the user is on-call with a far-end device or off-call; and wherein the system comprises a data communication unit for providing the determined heart rate data of the user, when the user is wearing the headset, for indication of the heart rate data of the user.

A hearing device configured to be worn by a user comprises one or more microphones, a processing unit, a speaker, a wireless communication unit, and stress evaluator. The user wearing the hearing device is in an environment defined by an acoustic scene. The microphones receive audio signals from audio sources in the environment and provide them to the processing unit which applies processing parameters to thereby process the audio signals. The speaker provides the processed audio signals to the user. The stress evaluator generates an indication of stress of the user, stress of the user being related to the acoustic scene. The processing unit then decides whether to perform an action on the basis of the received audio signals and the indication of stress of the user.

An illustrative insertion management system may be configured to monitor, during a lead insertion procedure in which an electrode lead having a plurality of electrodes is inserted into a cochlea of a recipient of a cochlear implant, impedance values for a subset of electrodes included in the plurality of electrodes, the subset of electrodes being less than a total number of the plurality of electrodes; detect, during the lead insertion procedure and based on the monitoring, an anomaly in the impedance values; and generate, during the lead insertion procedure and based on the anomaly, translocation log data indicating that a translocation event in which the electrode lead translocates from a first scala of the cochlea to a second scala of the cochlea is about to occur or has occurred during the lead insertion procedure.

User equipment is configured to collect biosensor data from an integrated biosensor or by receiving biosensor data from one or more external biosensors. The user equipment includes a Health Monitoring (HM) application. The HM application is configured to receive the biosensor data and display the biosensor data on the display of the user equipment. The user equipment may also communicate biosensor data over a local or wide area network to a third party, such as a pharmacy or health care provider.
