In this thesis, the implementation of a passive, chipless, frequency coded Radio-Frequency Identification (RFID) tag for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado river, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. The...

Bioreactors are used nowadays to produce proteins with therapeutical effect that can treat a new range of diseases in humans. Unfortunately, measuring protein concentrations directly inside bioreactors in real time is still an unsolved challenge. This is due the large amount of compounds that can be found inside the bioreactors that interfere...

This thesis describes the work of two students who designed the control system of a stand-alone water well measuring system, named SubDowser. The project was done by order of a proposal from the start-up company SkyDowser. The total thesis group, consisting of three subgroups, was asked to build a working prototype which could measure the water...

A sampled voltage reference aims to achieve both low-power and low-noise by storing the output of a voltage reference on a capacitor for a long time. This allows the reference to be switched off during the hold period, which leads to lower average power. At the same time, all the voltage reference's noise is pushed down into a bandwidth...

Temperature sensors are widely integrated in high performance systems, e.g. microprocessors. If the die temperature becomes too high, the processor must throttle its clock speed to prevent reliability problems. This application requires temperature sensors that can be integrated in the same advanced technologies as the microprocessor, and that...

This document describes the design and modification of a Universal Jamming Gripper. On the existing idea is expanded in such a way that it can be used in a low power environment. For the gripper a capacitive sensor is proposed to measure the deformation of the flexible part. This measurement can be used to aid in centring an object in the...

This thesis presents a new approach to reading out thermal-conductivity-based gas sensors. This method is intended for the readout of a CMOS compatible resistive thermal-conductivity transducer for indoor CO2 sensing applications, without requiring precision off-chip components. Instead of accurately regulating the power dissipated in the...

Dit verslag beschrijft het onderzoeken en ontwerpen van een krachtsensor voor een roeiboot. Het geleverde ontwerp wordt gezien als onderdeel van een totaalsysteem om het vermogen van een roeier te meten. Keuzes gemaakt in deze thesis zijn gemaakt met dit totaalsysteem in het achterhoofd gehouden. Na een korte blik op verschillende bestaande...

Op dit moment is er in de roeisport geen goedkope oplossing om het individuele vermogen van roeiers in de boot te meten en daarover nuttige informatie aan de roeiers te verstrekken. In deze scriptie is uitgezocht op wat voor manieren dit wel mogelijk zou zijn. Er worden meetsystemen op de roeiriem, op de dol en op de dolpen besproken om de...

The need for Cochlear Implants (CI's) with improved functionality and quality requires new techniques to be used to manufacture the electrode array. Titanium nitride (TiN) is one of the contenders for use as metal in the future CI's, but its characteristics need to be verified, measured and tested. A metal should comply to certain requirements...

This thesis presents an energy-efficient capacitive sensor interface based on a multi-slope analog-to-digital converter (ADC). This highly stable capacitance-to-digital converter (CDC) utilizes precision resistor as reference components. By utilizing a multi-slope analog-to-digital converter, the conversion time of this design is reduced down to...

Bandgap references are used in many ICs to produce ‘stable’ and ‘temperature-independent’ voltage. This thesis describes a sub-1V bandgap reference in 40 nm and 0.16 µm CMOS technologies that is functional from -40 oC to 125 oC. Traditionally, BJT based references are commonly used, but produce an output voltage of 1.2 V and are not suitable for...

Nowadays most of the energy needed comes from fossil fuels such as natural gas (NG). Dwindling stocks of all fossil fuels, including locally occurring natural gas reservoirs, have spurred the effort to both decrease dependence on local fuels and switch to renewable, green energy. The drawback to gas sources like Subsitute Natural Gas (SNG),...

In 2009, Department of Water Management (DWM) at TU Delft conceptualized the design of a low-cost disdrometer suitable for large scale, remote deployment. But, being a novel idea, its electrical characteristics were not well researched. Also, the system was not sensitive enough to measure the raindrops of diameter less than 0.9mm. Furthermore,...
