Biocompatible humidity sensor using paper cellulose fiber/GO matrix for human health and environment monitoring

Environmentally friendly humidity sensors with high sensing performance are considered crucial components for various wearable electronic devices. We developed a rapid-response and durable Paper Cellulose Fiber/Graphene Oxide Matrix (PCFGOM) humidity sensor using an all-carbon functional material. The fabricated sensor demonstrated a high...

Manufacturing of an In-Package Relative Humidity Sensor for Epoxy Molding Compound Packages

This study presents the design and fabrication of an in-package relative humidity sensor for epoxy molding compound (EMC) packages. The sensor comprises shielded interdigital electrodes (SIDE) for in-situ monitoring of humidity absorption/desorption in the package encapsulation layer. A novel approach is employed in the device fabrication to...

Energy-efficient capacitive-sensor interface based on an incremental Delta-Sigma modulator employing current-starved inverter-based OTAs

An interface circuit for a fully-integrated capacitive humidity-sensor is implemented using 0.16?m standard CMOS technology. This interface circuit is intended to be used in a smart RFID sensor platform. This thesis focuses on improving the energy-efficiency of the interface circuit. A third-order incremental delta-sigma converter based on...
