Title: Azmal Chowdhury: Innovator in Pressure Sensor Technology
Introduction
Azmal Chowdhury is a notable inventor based in Miami, FL (US). He has made significant contributions to the field of pressure sensor technology, holding a total of 3 patents. His work focuses on enhancing the sensitivity and functionality of piezo-resistive pressure sensors.
Latest Patents
One of his latest patents is a Multi-modal pressure sensor. This invention involves systems and methods that utilize finite element analysis to establish design rules for a highly sensitive piezo-resistive pressure sensor. The output of this sensor is designed to be high enough to be detectable by simple and inexpensive circuits, ensuring wearability. The patent details four frequently reported micro-feature shapes in micro-patterned piezo-resistive sensors, with the micro-dome and micro-pyramid shapes yielding the highest sensitivity. Investigations into different conductivity values of micro-patterned elastomers reveal that coating the elastomer with a conductive material, such as a metallic coating, results in a higher current response compared to composited conductive elastomers. The patent also provides advantageous geometric parameters and spatial configurations for the micro-pyramid design of piezo-resistive sensors. Results indicate that enhanced sensitivity and higher current output can be achieved with a lower spatial density configuration of three micro-features per millimeter length, a smaller feature size of around 100 μm, and a pyramid angle of 60-50 degrees.
