Abstract: Described herein is a force attenuator for a force sensor. The force attenuator can linearly attenuate the force applied on the force sensor and therefore significantly extend the maximum sensing range of the force sensor. The area ratio of the force attenuator to the force sensor determines the maximum load available in a linear fashion.

Abstract: Gravity-actuated display systems suitable for use as security markers, for example to incorporate into bank notes. The devices can be made very thin and flexible, yet are robust enough to endure the harsh conditions of paper currency in general circulation. Because the displays are gravity actuated, they do not require a power source or circuitry. The gravity-actuated displays can be fabricated using microembossing or photolithography and can be filled and sealed using roll-to-roll techniques. The microcells can also be patterned to provide custom designs, such as official seals.

Abstract: A sensor may include a deformable sensing element having a deformable conductor arranged to deform in response to deformation of the sensing element, wherein the deformation of the sensing element is selectively controlled. The sensing element may be selectively controlled by a restraining element. The restraining element may control the deformation of the sensing element by distributing forces applied to the sensing element. The sensing element may include a deformable body with the deformable conductor arranged to respond to elongation of the deformable body. The deformable conductor may include a conductive gel. A sensor may include a deformable body, a deformable conductor arranged to deform in response to deformation of the deformable body, and a restraining element arranged to selectively control the deformation of the deformable body.

Abstract: A force sensor includes first and second substrates. The second substrate faces the first substrate. A driving electrode is disposed on a first surface of the first substrate facing the second substrate. A sensing electrode is disposed on the first surface of the first substrate and is spaced apart from the driving electrode. A force sensitive layer is disposed on a first surface of the second substrate, facing the first substrate. The driving electrode includes a main driving protrusion that protrudes from a side surface of the driving electrode, facing the sensing electrode.

Abstract: The present disclosure describes internal force transducer balance system and related methods. One such system includes an internal balance having a cylindrical body extending axially along a longitudinal direction that includes an axial strain measurement component of the internal balance, wherein the axial strain measurement component is configured to measure an axial force applied to the internal balance. Disclosed he systems further includes an integral fluid flow path that continuously extends from the first end to the second end of the balance, wherein the integral fluid flow path is positioned in an interior core of the balance and is routed through the axial strain measurement component of the internal balance. The integral fluid flow path also comprises one or more turns as the integral fluid flow path is routed through the axial strain measurement component of the internal balance.
