Title: Innovations by Inventor Michael A. Huff

Introduction

Michael A. Huff, an accomplished inventor based in Medford, MA, holds a notable portfolio of three patented inventions. His work focuses on microvalve technology and pressure sensing devices, which have significant applications across various industries, including automotive and manufacturing.

Latest Patents

Among his latest patents, Michael has developed a **method of making a microvalve**, which features a multi-layered structure. This microvalve is unique as all layers are structured from one side only. Before bonding to the preceding layers, the new layer remains homogeneous. Once bonded, it undergoes structuring via etching or profiling, simplifying the construction process and reducing manufacturing costs. This innovative valve is adaptable for both liquid and gaseous media, making it suitable for applications such as fuel injection and pilot control stages in anti-lock braking systems (ABS). His patent also includes a method for producing a sealed cavity with residual gas pressure, which has potential applications beyond valve manufacturing.

Another noteworthy patent is the **micromachined threshold pressure switch and method of manufacture**. This pressure-activated switch features two electrodes across a cavity, with one made from a mechanically compliant material. Upon uniform pressure application, the compliant electrode buckles, closing the switch at a specific threshold. This design exhibits mechanical hysteresis, allowing it to reopen under a lower pressure. The switch is fabricated using wafer-to-wafer silicon bonding and conventional integrated manufacturing steps, ensuring tight dimensional control and customizable activation pressures. Potential applications for this switch include pressure sensors for automotive tires, tank pressure monitors in compressors, keyboard pads, weight detectors, and robotic tactile sensor arrays.
