Title: Gregory Ernest Poirier: Innovator in Microcalorimetry and Atomic Force Microscopy
Introduction
Gregory Ernest Poirier is a notable inventor based in Potomac, MD (US). He has made significant contributions to the fields of microcalorimetry and atomic force microscopy, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Micron-scale differential scanning calorimeter on a chip." This invention allows for microscopic scanning calorimetry measurements of small samples and thin films. The chip can be fabricated using standard CMOS processes, featuring a reference zone and a sample zone that may be positioned on separate platforms. An integrated polysilicon heater provides heat to each zone, while a thermopile generates a voltage representing the temperature difference between the zones. This technology provides valuable information about chemical reactions and phase transitions in samples.
Another significant patent is the "Atomic force microscope using piezoelectric detection." This method and apparatus enable the detection of surface properties of a sample using an atomic force microscope. The design includes a piezoelectric tube mounted on a rigid surface, which is divided into actuator and sensor segments. The sensor segments can detect interatomic force information without the snap-in effects that are common with cantilever mounts. A probe tip interacts with the interatomic forces of the sample surface, supported by circuitry that operates in either current feedback or force feedback modes.
