摘要： Disclosed is a measuring device for measuring a physical quantity. The physical quantity could be a pressure and/or a force. The measuring device comprises a circular sensing structure comprising a membrane section which is deflected by force variations acting on the circular sensing structure. A first and second strain gauge are attached to the membrane section. The first strain gauge is configured to measure radial strain in a first surface area of the membrane section. The second strain gauge is configured to measure tangential strain in a second surface area of the membrane section. An increase in force acting on the sensing structure results in shrinking of the first surface area measured by the first strain gauge and stretching of the second surface area measured by the second strain gauge.
