Each sensor module includes one or more sensors operably attached to a substrate. The one or more sensors are operable to detect strain on the substrate. One or more portions of the substrate are removed to produce a stress concentration region in proximity to at least one sensor. The stress concentration region concentrates strain in proximity to the at least one sensor.

A sensor chip includes a substrate, first supporting portions, a second supporting portion around which the first support portions are disposed, the second supporting portion being disposed at a center of the substrate, first detecting beams each connecting the first supporting portions, which are mutually adjacent, second detecting beams disposed in parallel with the first detecting beams between the first detecting beams and the second supporting portion, force points disposed in the first detecting beams so as to be applied with force, and a plurality of strain detecting elements disposed a predetermined positions of the first detecting beams and the second detecting beams, wherein the plurality of strain detecting elements includes a first detecting portion having a strain detecting element capable of detecting force in a first direction, and a second detecting portion having a strain detecting element disposed at a position symmetric relative to the first detecting portion.

A sensor and method for use in measuring a physical characteristic of a fluid in a microfluidic system is provided. A microfluidic chip has a thin deformable membrane that separates a microfluidic channel from a microwave resonator sensor. The membrane is deformable in response to loading from interaction of the membrane with the fluid. Loading may be fluid pressure in the channel, or shear stress or surface stress resulting from interaction of the membrane with the fluid. The deformation of the membrane changes the permittivity in the region proximate the sensor. A change in permittivity causes a change in the electrical parameters of the sensor, thereby allowing for a characteristic of the fluid, such as flow rate, or a biological or chemical characteristic, to be measured. Also, a microwave sensor with improved sensitivity for characterizing a fluid in a microfluidic channel is provided. The sensor has a rigid and very thin layer, for example in the range of 10 um to 100 um, in the microfluidic chip allowing for the positioning of the sensor very close to the microfluidic channel, which enables very high resolution sensing.

An apparatus for sensing a physical attribute is shown, that includes a first track (511) defining a first electrode on a substrate (512), a second track (513) defining a second electrode on said substrate and an active film (514) in cooperation with a first sensor portion (516) of the first electrode and a second sensor portion (517) of the second electrode. The second electrode includes a first extended portion (517) to establish a first additional resistance not cooperating with the active film.
