Electronic noses (e-nose) have been studied for several years and extensively applied; however, they are limited by their volume and high manufacturing cost. Portable devices have become popular in recent years; therefore, it is crucial to integrate e-noses in portable devices (e.g., mobile phones). This study used TSMC 90nm 1P9M CMOS MSG technology to develop a front-end system-on-chip (SoC) for...
The bulkiness of current electronic nose (E-Nose) systems severely limits their portability. This study designed and fabricated an E-Nose signal-processing chip by using TSMC 0.18- m 1P6M complementary metal–oxide semiconductor technology to overcome the need to connect the device to a personal computer, which has traditionally been a major stumbling block in reducing the size of E-Nose systems...
The portable electronic nose system is composed of a sensor array (sensor head) part and an electronics part. The sensors are made of polymer/mesoporous carbon composite materials for high sensitivity and selectivity. The electronics are sensor interface circuitry together with a microprocessor.
Bio-medical implantable devices have appeared for more than fifty years. With more understandings of neuroscience, some diseases caused by neural abnormal discharge or disable may be cured or improved by neural stimulation techniques. Most of the wireless implantable devices transmit power and data into the no-battery implantable device by magnetic coupling. This paper presents an efficient power...
