Graphene is an attractive material to be used for pressure sensors due to its thinness, electrical conductivity, and potential high gauge factor. One of the issues with processing graphene is the scalability, which is largely limited by the transfer process that is required for graphene deposited by chemical vapour deposition (CVD). In this work...

Endoscopic devices are used in the medical world to inspect the gastrointestinal tract. Because there are some complications with wired endoscopy, such as reaching the small intestine, there is a need for new methods to do endoscopy. Therefore an endoscopic pill is invented which can be used to do measurements in the gastrointestinal tract. This...

At this time, sensor developers rely on their own circuit board designs to test new sensors. This means a lot of time and money is spent on designing the custom interface for every newly designed sensor. This report describes a way to have a configurable test bench for sensors. The system consists of a data acquisition unit and multiple circuit...

Smart temperature sensors can be used for the temperature compensation of micro-electromechanical (MEMS) frequency references. From the different types of CMOS temperature sensors, resistor-based sensors are currently the most energy-efficient. However, compared with bipolar transistor (BJT)-based temperature sensors, resistors suffer from...

Buildings don’t use energy: People do. Do highly efficient homes really save energy? Counter-intuitively, dwellings that use less energy have low energy efficiency, and those with higher energy consumption have higher efficiency. Moreover, even accurate building energy simulation for multiple buildings could not predict the actual energy...
