A portable, non-invasive and easy to operate wireless system has been developed for monitoring the breathing activity of patient. The system is composed of a capacitive microsensor (airflow-humidity sensor) integrated on a silicon chip and of a Negative Temperature Coefficient thermistor; both are connected to a wireless network to allow efficient healthcare at home as well as in hospitals. The capacitive...
The design, fabrication, and application of a monolithically integrated array of chemical sensors is presented. The multisensor chip includes six independent ion selective field effect transistors (ISFETs), a pair of interdigitated platinum electrodes, and a diode temperature sensor. Simultaneous polarization of multiple ISFETs is enabled by electrical isolation of the devices using two different...
