Abstract
Apparatus are provided for sensor assemblies and related medical devices. An embodiment of a sensor assembly includes a rigid structure and a beam structure having an outer portion in contact with the rigid structure and an inner portion. The beam structure includes one or more beams extending between the outer portion and the inner portion of the beam structure and a cantilevered portion extending from the inner portion to inhibit displacement of the inner portion toward the rigid structure. Each beam has a sensing element disposed thereon.
Claims5
A sensor assembly, comprising:
- a back plate structure;
- a beam structure comprising:
- an outer portion affixed to the back plate structure;
- an inner portion;
- a plurality of arm portions between the outer portion and the inner portion, each arm portion having a sensing element disposed thereon;
- and
- a plurality of cantilevered portions extending radially outward from the inner portion, the cantilevered portions being freestanding with respect to the outer portion;
- and
- a loading element mechanically coupled to the inner portion, the loading element to displace the inner portion towards the back plate structure with respect to the outer portion in response to a force applied to the sensor assembly, the cantilevered portions impeding displacement of the inner portion when the force applied to the sensor assembly is greater than a threshold value.
