Systems and methods for pressure measurement are provided. A ludion with a trapped gas bubble floats between two liquids. Pressure acting upon the liquids causes the bubble to expand or contract, resulting in movement of the ludion which can be measured and correlated with pressure change. Pressure measuring device can measure pressures from 0.05 inHg to 110 inHg with a four-to-one Test Accuracy Ratio (TAR) without using mercury.

The present invention relates to a thermoplastic mask monitoring system using a pressure sensor. Specifically, a thermoplastic mask according to the present invention may include: a mask having a shape determined according to a shape of a first region which is at least a part of a patient's body by using thermoplasticity, fixing the first region in close contact with the first region, and receiving radiation; and a pressure sensor provided between the mask and the first region and sensing pressure induced by a space generated between the mask and the first region.

Contact-force-sensing systems that can provide additional information about the forces that are applied by catheters and other devices to cell walls and other surfaces. One example can provide directional information for a contact-force-sensing system. For example, magnitude, plane angle, and off-plane angle information can be provided by a contact-force-sensing system. Another example can provide guiding functionality for a contact-force-sensing system. For example, a contact-force-sensing system can provide tactile response to a surgeon or operator to allow a device to be accurately guided though a body.
