Measurement system with controlled pressure ramp

A measurement system comprising:

• a pressure resistant structure including a band and a body;
• a pressure inducer coupled to the band, the pressure inducer having an activation layer, and a shape-memory layer, the shape-memory layer configured to have a shape-set state and a deformable state, the activation layer configured to induce the shape-memory layer into the shape-set state and increase pressure exerted on a portion of a user in contact with the pressure resistant structure;
• a light source coupled to the body;
• an optical sensor coupled to the body and configured to detect a signal from the light source;
• a pressure sensor coupled to the pressure resistant structure, the pressure sensor configured to detect the pressure exerted on the portion of the user in contact with the pressure inducer;
• and
• a processor coupled to the optical sensor and the pressure sensor, the processor configured to correlate volumetric data from the optical sensor with pressure data from the pressure sensor and to provide a blood pressure measurement.

A method of manufacturing a measurement system comprising:

• providing a pressure resistant structure;
• coupling a pressure inducer to the pressure resistant structure, the pressure inducer having an engaged configuration, the engaged configuration of the pressure inducer increasing pressure exerted on a portion of a user in contact with the pressure resistant structure;
• coupling a light source to the pressure resistant structure;
• coupling an optical sensor to the pressure resistant structure and configured to detect a signal from the light source;
• coupling a pressure sensor to the pressure resistant structure, the pressure sensor configured to detect the pressure exerted on the portion of the user in contact with the pressure inducer;
• and
• coupling a processor to the optical sensor and the pressure sensor, the processor configured to correlate volumetric data from the optical sensor with pressure data from the pressure sensor and to provide a blood pressure measurement.
