Abstract: Embodiments are directed to a blood pressure measurement device that includes a strap operable to couple the blood pressure measurement device to a user and a pump coupled to the strap. In some embodiments, the blood pressure measurement device includes an inflatable chamber fluidly coupled to the pump and positioned between the pump and the user when the blood pressure measurement device is coupled to the user. The inflatable chamber can be configured to expand towards the user when inflated. The blood pressure measurement device can include a sensing chamber coupled to the inflatable chamber and configured to be placed between the inflatable chamber and the user; a pressure sensor positioned in the sensing chamber and configured to detect a pressure of the liquid; and a vibration sensor positioned in the sensing chamber and configured to detect vibrations due to blood flow of the user.

Abstract: An electronic device, such as a smart watch, incorporating a fluid-based pressure-sensing device is disclosed. The fluid-based pressure-sensing device includes an enclosure, a pressure sensor, a diaphragm and a sensing medium. The enclosure includes an opening and the pressure sensor is disposed inside the enclosure. The diaphragm hermetically seals the opening, and the sensing medium transfers a pressure exerted on the diaphragm to the pressure sensor. The sensing medium can be liquid oil filling a space of the enclosure, and the diaphragm is a polymer material. The pressure-sensing device may sense an environmental pressure, which may be used by the electronic device to modify its operations, change information that is displayed, and so on.

Abstract: Embodiments are directed to a blood pressure measurement device that includes a strap configured to couple the blood pressure measurement device to a user, an air pump coupled to the strap and having a housing defining a surface facing the user, and an inflatable chamber positioned on the surface of the air pump and fluidly coupled to the air pump. The inflatable chamber can be positioned between the air pump and the user when the blood pressure measurement device is worn by the user and expand towards the user when inflated. The blood pressure measurement device can also include a pressure sensing chamber coupled to the inflatable chamber and positioned between the inflatable chamber and the user when the blood pressure measurement device is worn by the user. The pressure sensing chamber can include a liquid volume and a pressure sensing device configured to detect a pressure of the liquid volume.

Abstract: A sensor module includes a container. The container has a closed wall extending between a first end of the container and a second end of the container. An exterior of the closed wall at least partly defines a seal-receiving channel. The seal-receiving channel extends around a circumference of the closed wall. The sensor module also includes a pedestal positioned between the first end and the second end and at least partly defining a first compartment and a second compartment surrounded by the closed wall. The sensor module further includes a sensor die positioned within the first compartment and mounted on the pedestal.
