This abstract first appeared for US patent application 20250123163 titled 'DIRECT FORCE SENSING ON A THIN PLATE, FOR TRANSVERSE, UNEVEN PRESSURE FIELDS
Original Abstract Submitted
dual loop strain gauge architectures (or other multiple loop strain gauge architectures) are used to sense an amount of force applied to an electronic device. the force may be applied by a transverse, uneven pressure field, such as a force that is applied by an amorphous object and/or a force that is applied non-uniformly, over a large area and/or to multiple points or areas. in some embodiments, a dual loop (or other multiple loop) strain gauge architecture is used to sense a pressure distribution on an electronic device. in some embodiments, a single loop strain gauge architecture is used to sense an amount of force applied to an electronic device.
