Abstract: A strain sensing apparatus including a deformable substrate is presented. The deformable substrate is configured to detect a strain of the body that can be coupled to the deformable substrate. Sometimes, the deformable substrate is a flexible substrate having an upper surface and an opposite lower surface. The lower can be coupled to the body. There are sensing elements fabricated within the flexible substrate and proximate to the upper surface to detect properties of the body. The strain sensing apparatus is able to detect different strain modes, such as whether the strain is the result of bending of a body or a uniaxial elongation. Furthermore, the apparatus is small and less fragile than most conventional sensors, making it easy to use.

Abstract: The present invention relates to a pressure measuring apparatus, characterized in that: the pressure measuring apparatus comprises a pressure sensor having a first resistor for sensing an external stress and a second resistor acting as a reference, wherein the second resistor is acting as a reference while the first resistor is used for measuring an external stress in that a first oscillating signal received by an end of the first resistor is affected by the external stress, and consequently an affected first oscillating signal varied with respect to the external stress is outputted from the other end of the first resistor, and a second oscillating signal received by an end of the first resistor is outputted from another end of the second resistor without being affected by the external stress. Hence, the present invention provides a pressure measuring apparatus and a pressure sensor thereof using the frequency difference of the oscillating signal in accordance to the variation of the resistor value as base for measuring the external stress. Hence, the present invention requires no amplifier and A/D converter so that the whole manufacturing process is simplified and also the overall cost of the pressure measuring apparatus is reduced.

Abstract: A new extensometer is disclosed that avoids prior art problems of drift and other problems from variations in temperature, humidity and other environmental factors. Two primary extensometer body parts each hold at one end specimen contact rods and at their other ends a displacement measuring sensor, preferably a linear variable differential transformer. A thin hinge area connects the two body parts into a single piece monolithic construction so that relative movement between the two body parts is restricted to a single rotational degree of freedom.

Abstract: A strain sensor improved in detection accuracy without variation of bending stresses applied to the strain detecting element. The sensor substrate has a first fixing hole at one end and a second fixing hole at the other end, a detecting hole at the center, and at least one strain detecting element on the upper surface or lower surfce thereof. The first fixing member is press-fitted into the first fixing hole. The second fixing member is press-fitted into the second fixing hole. The detecting member is press-fitted into the detecting hole. Further, when an external force is applied to the detecting member, strain generated due to the positional shift of the detecting member is detected by the strain detecting element with respect to the first fixing member and the second fixing member.
