The present disclosure provides computer-implemented methods, systems, and devices for improved skin temperature monitoring. Accurate estimates of skin and ambient temperature are generated based on determinations and comparisons of skin and internal device temperature sensor measurements contained on or within example devices. The estimates of skin and ambient temperature measurements facilitate monitoring skin and core temperature changes, detecting physiological events of a wearer of example devices, and determining when skin temperature changes are environmentally or physiologically induced.

Methods, systems, and devices for improved skin temperature monitoring

The accuracy of physiological data measured through contact with skin can be validated by characterizing the forces at the surfaces where data is measured. Conventional devices do not monitor the fit of skin-based sensors, making the accuracy and confidence in physiological data dependent on the user ensuring that the device is fitted properly. Over time, the seating of a device will vary due to changes in user activity and the need to periodically remove a device. Inevitably, instances will arise where the device is not fitted correctly, which may result in skewed physiological metrics. By monitoring the forces acting on the housing of a device, the interface of skin sensors can be characterized allowing for confidence metrics in the corresponding physiological data to be determined. In some cases, a user can be notified when a device is not seated properly, and in some cases, data may even be calibrated based on the fit of a device.

Pressure sensor integration into wearable device

Disclosed herein is a ring-shaped wearable device for detecting biometrics with a light source and a photodetector directed towards a digit wearing the ring-shaped device. The ring can thus detect oxygen saturation of a wearer based on light transmitted through the wearer's finger. The ring can include power saving measures to extend the battery life. A motion sensor can help determine opportune moments for data collection such as when the wearer is still. The motion sensor can be used to remove noise from the data caused by motion. After data is collected or during data collection, the ring can wirelessly communicate the data to another portable electronic device such as a phone or watch.

Ring for optically measuring biometric data

Various embodiments provide a wellness tracking device with a base plate that may be utilized as a combination electrode by a variety of sensors. The base plate may be a multi-material electrode that includes a conductor and a transparent or semi-transparent material to enable optical sensing. In certain embodiments, the base plate supports a plurality of different sensors, which may selectively utilize the base plate as an electrode.

Methods and systems for combination electrodes for wearable devices

Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.

Integrated ECG electrode and antenna radiator

Arousal events can be determined for a user associated with a wearable device, such as a user wearing a wearable computing device including one or more sensors. The one or more sensors may obtain EDA information that may determine a sympathetic nervous system response of the user, which may be responsive to an arousal event or an activation. Detection of events that increase the EDA response may provide information to the user regarding arousal events and provide recommendations to the user to address the arousal events to decrease their response.

Detection and response to arousal activations

Sleep tracking systems and techniques for monitoring two or more co-sleepers in a single bed are disclosed. Such systems and techniques may incorporate sleeper identification, as well as various non-user-specific aspects. Some implementations may incorporate user-specific or user-tailored alarm functionality.

Sleep monitoring system with optional alarm functionality

Low-profile latching mechanisms and related mechanical interfaces for allowing straps and other fastening accessories for limb-wearable devices are provided. The mechanisms in question allow for a very strong, yet easily releasable, connection to be made between a strap accessory and a device housing, with very little of the mechanism being visible.

Wearable device straps and attachment hardware therefor

Systems and devices of the present disclosure provide automated detection and tracking of carbon monoxide inhalation through non-invasive optical spectroscopy. A wearable device includes a light source coupled to the base and directing light towards a subject and a photodetector coupled to the base to receive light emitted by the light source through or reflected the subject. The light source emits light at a wavelength spectrum corresponding to a carboxyhemoglobin absorption spectrum and an oxyhemoglobin absorption spectrum. Biometric circuitry is coupled to the photodetector to receive a signal from the photodetector and process the signal to determine an intensity of the wavelengths present in the light received at the photodetector. The intensity of the wavelengths is indicative of a level of carbon monoxide inhalation associated with the subject.
