Abstract: An interface pressure sensor includes a fluid pressure sensor disposed in a volume defined by a shear wall. The volume is enclosed, and the fluid pressure sensor is encapsulated by, an infill material. The infill material defines a sensing surface that, when pressed, can impart a force that is detectable by the fluid pressure sensor.

Abstract: Disclosed herein are capacitive sensors, and methods for their operation, that determine the presence of a user by detecting input forces and/or pressures. Capacitive sensors may be in the form of a flexible capacitive sensing mat. An electronic device incorporating a flexible capacitive sensing mat may include spacer fabric disposed between conductive layers. The spacer fabric may have a first thickness and may be configured to compress to at least a second thickness when a threshold pressure is applied to the layered sensor and revert to the first thickness when the threshold pressure is no longer applied to the flexible mat. A capacitive sense circuit electrically coupled to the second conductive layer and configured to generate a presence detection signal when the spacer fabric layer compresses to the second thickness may additionally be provided.

Abstract: The present disclosure generally relates to wearable devices and methods for measuring a photoplethysmographic (PPG) signal. The wearable devices and methods described herein are capable of obtaining PPG signals by employing a PPG sensor array configured to receive light at angles associated with a high perfusion index. Viewing components may be coupled to the PPG sensor array to effect transmission of light at these preferential angles.

Abstract: An electronic device includes one or more light emitters for emitting light toward an object and one or more light detectors for collecting light exiting the object. A reflective coating, surface, or surface finish can be applied adjacent to the area to which light is emitted and/or through which light exits in order to increase the light collected by the light detector. The reflective coating can be oriented so as to reflect light back into the object.

Abstract: A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.
