Disclosed herein are monitoring systems and sensors for physiological measurements. The sensors can be multi-element piezo sensors capable of generating multiple electrical signals, whereby the monitoring systems can receive the multiple electrical signals to analyze the user's vital signs along multiple regions of the user's body. In some examples, the piezo sensor can include one or more corrugations, such as peaks and valleys, to create localized regions with increased mechanical response to force. The sensitivity and resolution of the piezo sensor can be enhanced by further locating electrode sections at the corrugations, where the electrode sections can be electrically isolated and independently operable from other electrode sections. Traces electrically connecting an electrode section to, e.g., an off-panel controller can be routed over and/or around other electrode sections by including an insulator to electrically insulate from the other electrode sections, or by using vias to route through one or more layers.

Multi-element piezo sensors for physiological measurements

A monitoring system configured to measure the user's health-related parameters while in a certain state is disclosed. Based on whether the user is in the certain state and/or one or more criteria being met, the monitoring system can perform a physiological measurement such as a blood pressure measurement. The monitoring system can be capable of dynamically adjusting the measurement parameters, criteria, and acquired information based one or more scalers. The criteria can be based on user states or conditions such that user disruptions can be reduced and the measurement accuracy and/or efficiency can be enhanced. The monitoring system can also measure the user's parameters during the measurement and may abort the measurement if the measurement may not have accurate information and/or to reduce any disruption to the user. Alternatively, the measurement can be annotated so that the measurement can be used during data interpretation with certain qualifiers attached.
