Latest Patents: Among Stephen P. Long's notable inventions is a method of making pressure sensor assemblies. This innovation utilizes silicon-based high-pressure sensor modules that are arranged in an array. A key feature of this design is the low-temperature co-fired ceramic (LTCC) substrate, which is engineered to withstand high pressures. The sensor cells, housed within bossed containers filled with oil, are crafted from a sensor handle wafer and a diaphragm. The flexible top surfaces of these bossed containers deflect under pressure, allowing for precise measurement of a wide range of pressures. The oil acts as a protective medium, transferring pressure to the diaphragm while safeguarding the sensor cell from extreme conditions.

Additionally, Long has developed a compact sensor module which features a robust housing containing a sensor. This module also incorporates a low-temperature co-fired ceramic substrate on which both the sensor and signal processing circuitry are integrated. The design includes a metal shield that encapsulates the sensor, ensuring its durability and performance in demanding environments.
