Abstract:
An integrated adhesive sensor array includes an adhesive a patch, a sensor hub, and a detachable sensor pod packaged as a unit. The patch may include a docking area for the detachable sensor pod. The detachable sensor pod may include at least one sensor and may be configured to be detached from the patch and applied to various locations on a body. The detachable sensor pod may send sensor data to the sensor hub via a wired link when on the patch and via a wireless link when detached from the patch. The sensor hub receives sensor data from the detachable sensor pod and relays the data to a receiver. The sensor hub and detachable sensor pod may include indicators for communicating information. The sensor hub may include a power source for powering the sensor hub and a detachable sensor pod attached to the main sensor unit or patch.
Abstract:
A wearable device may include a sensor system capable of obtaining physiological from a user's body. Some wearable devices may include a substance delivery system. A sensor system of a wearable device may include at least one “bio-assurance sensor” capable of obtaining biometric data that may be used to identify a user. For example, the bio-assurance sensor may be used to ensure that the wearable device is not removed from the user's body and/or placed on or in another user's body. In some examples, the wearable device may be used with a second device, such as a smart phone, that includes at least one “authentication sensor,” such as a fingerprint sensor, that also may be used to identify a user. However, in some implementations the wearable device may include at least one authentication sensor.
Abstract:
Methods, systems and devices for an energy harvesting sensor are disclosed. A sensor device may include an energy harvesting element configured to harvest energy from a source of energy that is to be measured by the sensor device, and an energy storage element configured to store energy generated by the energy harvesting element. The sensor device may further include a transmitter circuit coupled to the energy storage element and configured to transmit a wireless signal when the energy stored in the energy storage element is sufficient to power a transmission of the wireless signal. The time between transmissions by the transmitter may be used by a receiver of those transmissions to calculate a measure of the quantity being used for energy harvesting.

Abstract:
A wearable otoscope may be capable of wireless or wired communication with a second device, such as a smart phone. Some dual-ear otoscope implementations may be provided in a headphone-like configuration, which may include a headband attachable to earbuds of the dual-ear otoscope. However, some alternative implementations do not include a headband. At least a portion of the dual-ear otoscope may be a disposable component in some examples. In some implementations, functionality of the dual-ear otoscope (such as an illumination angle of light, imaging functionality, etc.) may be controlled according to commands received from the second device. Some examples may include one or more additional sensors, such as temperature sensors.
Abstract:
Some implementations provide a semiconductor device that includes a first die and an optical receiver. The first die includes a back side layer having a thickness that is sufficiently thin to allow an optical signal to traverse through the back side layer. The optical receiver is configured to receive several optical signals through the back side layer of the first die. In some implementations, each optical signal originates from a corresponding optical emitter coupled to a second die. In some implementations, the back side layer is a die substrate. In some implementations, the optical signal traverses a substrate portion of the back side layer. The first die further includes an active layer. The optical receiver is part of the active layer. In some implementations, the semiconductor device includes a second die that includes an optical emitter. The second die coupled to the back side of the first die.

Abstract:
A stethoscope system may include an array of sensors, which may include pressure sensors. The array may be implemented in a wearable “patch” that is conformable to a patient's body. The stethoscope system may include a control system that is capable of receiving signals from the array of sensors. The signals may, for example, correspond to measurements from multiple pressure sensors of the array. The control system may be capable of combining signals from multiple pressure sensors to produce combined signals. The control system may be capable of filtering the combined signals to remove, at least in part, breathing signal components and to produce filtered signals. The control system may be capable of determining a correspondence between heart signal components of the filtered signals and corresponding heart valve activity.
