Force sensor assembly with stress isolation

Abstract

A force sensor assembly includes stress isolation features/geometry that blocks out unintended/off-axis forces/stress that would normally create an inaccurate force output. The force sensor assembly is a relatively low cost, high volume, weight minimizing design using robust automotive grade technology and is easily integrated into various applications due to a platform design approach. The piezoresistive MEMS are placed on stainless steel, which are minimized to allow for mass/cost reduction, therefore the other parts (PCB, element cover, customizable force bar) in the assembly are also minimized to allow for mass/cost reduction. The assembly is a simple 3-piece assembly that is easily integrated with minimal assembly processes. The automotive grade technology referenced is high pressure piezoresistive MEMS technology.
