Abstract: Technologies for multimodal sensing include a wearable device having a flexible substrate and at least one multimodal sensor coupled to the flexible substrate. The multimodal sensor includes a photoplethysmography sensor and a bioimpedance sensor. The wearable device may include context sensors such as an accelerometer, a gyroscope, a temperature sensor, or a pressure sensor. The multimodal sensor may include an integrated pressure sensor. A processor of the wearable device is configured to receive sensor data from the photoplethysmography sensor and the bioimpedance sensor of the multimodal sensor that is indicative of a pulse curve of a user. The processor is further configured to correct the sensor data based on data received from the context sensors and to determine blood pressure data based on the corrected sensor data. The processor may be configured to store the blood pressure data or to transmit the blood pressure data to a remote computing device.

Abstract: Wearable optical devices, methods and systems for obtain dynamic and static physiological parameters from a subject are disclosed. Example devices can be worn around an appendage, such as a finger, and utilize PPG sensors to obtain signals from the appendage. The PPG sensors are positioned to acquire signals suitable to reconstruct an image of the inner appendage using, for example, diffuse optical tomography, to provide additional information. The devices, methods, and systems can obtain dynamic and static physiological parameters and accurate images in real-time.
