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. The interface pressure sensor can be used for applanation tonometry.

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: Embodiments are directed to a blood pressure measurement device including a cuff that is operative to wrap around a limb of a user, a bladder coupled to the cuff and operative to compress the limb of the user when inflated, and a piezoelectric sensor coupled to the cuff and operative to detect blood flow through the limb of the user and output a signal indicative of the blood flow. The blood pressure measurement device can also include a processor coupled with the piezoelectric sensor that is operative to filter the signal to isolate sounds corresponding to changes in the blood flow through the limb due to inflation of the bladder, correlate the isolated sounds with a pressure inside the bladder, and determine a blood pressure of the user at least partially based on correlating the isolated sounds with the pressure.

Abstract: Embodiments described herein are directed to a temperature measurement device that includes a sensor body configured to be placed on a skin of a user. The temperature measurement device can include a first section defining a first lower surface and having a first thickness, a second section defining a second lower surface and having a second thickness, and a channel separating the first lower surface from the second lower surface. The temperature measurement device can also include a first set of temperature sensors positioned across the first thickness, a second set of temperature sensors positioned across the second thickness, and a processor configured to estimate a tissue temperature of the user based on comparing temperature signals from the first set of temperature sensors with temperature signals from the second set of temperature sensors.

Abstract: An in-bed haptic device may include an array of actuation cells. Actuation cells of the array of actuation cells may be configured to actuate (e.g., expand, contract, or otherwise change shape) in a predetermined sequence to provide haptic outputs. The in-bed haptic device may be configured to be placed beneath a user during use, for example between a user and a mattress. The haptic outputs may be provided to help a user relax, to move and/or wake a user, to indicate outputs, alerts, or notifications at the in-bed haptic device or another electronic device, or the like.

Abstract: The present invention generally relates to blood pressure monitoring. In some embodiments, methods and devices of measuring a mean arterial pressure are provided and/or monitoring blood pressure changes. A wrist-worn device may include a plurality of sensors backed by a plurality of actuators. Subsets of the plurality of sensors may be selectively actuateable against a wrist of a user using one or more of the plurality of actuators. A preferred sensor and location may be identified based on pressure signals received from each of the sensors. In some embodiments, devices may use a fluid bladder coupled with piezoelectric film sensors. A fluid bladder pressure sensor may be used to calibrate the piezoelectric film signal to provide a static and dynamic pressure reading. In yet another embodiment, a mean arterial pressure may be calculated by processing a swept pressure signal obtained as a sensor is swept through different heights.

Abstract: Wrist-worn devices and related methods measure a pulse transit time non-invasively and calculate a blood pressure value using the pulse transit time. A wrist-worn device includes an accelerometer, a photo-plethysmogram (PPG) or a pulse pressure sensor, and a controller. The PPG or the pulse pressure sensor coupled to the wrist-worn device for detecting an arrival of a blood pressure pulse at the user's wrist. The controller is configured to process output signals from the accelerometer to detect when the blood pressure pulse is propagated from the left ventricle of the user's heart, process a signal from the PPG or the pulse pressure sensor to detect when the blood pressure pulse arrives at the wrist, calculate a pulse transit time (PTT) for propagation of the blood pressure pulse from the left ventricle to the wrist, and generate one or more blood pressure values for the user based on the PTT.

Abstract: The present invention generally relates to the measuring and monitoring of blood pressure. More specifically, embodiments may apply the theory of applanation tonometry for the measurement of blood pressure. Some embodiments provide a method for measuring mean arterial pressure. Some embodiments provide a device that may be worn by a user that may non-invasively measure and monitor blood pressure of a user. In some embodiments, the invention generally relates to sensor arrays for use with a wrist-worn device to measure blood pressure. Embodiments of the sensor array designs described may be configured to improve resolution by decoupling nodes of the sensor array.
