A medical sensor is disclosed for mounting within a medical device. In one embodiment, more than one medical sensor is mounted to a printed circuit board using surface mount technology to accurately place the medical sensors in predetermined positions. The medical sensor is a sensor for measuring a force, pressure, or load. The medical sensor is manufactured in a process that supports consistency, matching, reliability, and performance. The medical sensor comprises a substrate, a dielectric layer overlying the substrate, and four strain gauges overlying the dielectric layer. Interconnect and pads are formed overlying the dielectric layer. The interconnect couples the four strain gauges into a full bridge Poisson gauge and couples the pads to the full bridge Poisson gauge. The active strain gauges are placed in a predetermined location on the substrate that support measurement of a force, pressure, or load applied to the substrate.

A force/torque sensor includes a plurality of serpentine or spiral deformable beams connecting a TAP and MAP. These classes of shapes increase the overall length of the deformable beams, which reduces their stiffness. In addition to the deformable beams is a plurality of straight overload beams, each connected at a first end to one of the TAP and MAP, and separated from the other of the TAP and MAP at the second end by an overload gap of a predetermined width. Over a first range of forces and torques, strain gages on the deformable beams transduce compressive and tensile strains into electrical signals, which are processed to resolve the forces and torques. Over a second range of forces and torques greater than the first range, the overload beams close the overload gap, establishing rigid contact to both the TAP and MAP. The stiffness of the sensor in the second range of forces and torques is greater than over the first range.

A force sensor, flexible sensing element, and method for the force sensor are disclosed. The force sensor uses a flexible sense element with two flexible arms dedicated to measuring strain related to a pitch force and two flexible arms dedicated to measuring strain related to roll force. The use of two channels for each measurement provides a command lane and a monitor lane for strain measurements. Strain gauges are disposed on both the top and the bottom surfaces of each arm, thus providing two completely redundant systems. When a failure is detected in one of the systems, the redundant system can be implemented.

A bi-directional force sensor which includes a first body and a second body. The first body has a first portion and a second portion. The second body also has a first portion and a second portion. The second body interlocks with the first body with the first portion of the second body positioned between the first portion and the second portion of the first body and the second portion of the first body positioned between the first portion and the second portion of the second body. A first sensor is positioned between the first portion of the first body and the first portion of the second body. A second sensor is positioned between the second portion of the first body and the first portion of the second body.
