A Surface EMG System: Local Muscle Fatigue Detection

In the last 4 decades, surface electromyography (sEMG) signal processing has been applied to detect local muscle fatigue, this non-invasive approach is suitable for detecting EMG signals generated by athletes in motion. Also, EMG could directly reveal the muscle’s performance like endurance and recruitment of motor units, which is hard to be...

Instrumented Skeleton Sled: Focussing on force and orientation sensing

This report details the design of an instrumentation system to be used on a skeleton sled. The system will measure data during the run on a skeleton track using several sensors and process and visualise the data afterwards in order to shorten the learning curve of the athlete and give quantitative feedback. The subsystem discussed in this report...

A Capacitive Implementation of an Online Sensor Grid for Measuring Grease Deposition in Extraction Channels

An extraction channel cleaning company wanted a grease thickness sensor to be developed that would send the data via the internet so that information on the thickness could be accessed remotely. This system consists of two parts: the sensor part and a communications part. This report is on the sensor part, which uses a change in capacitance of...

Wired sensor network for measuring fat deposition in extraction channels: A Power Supply and Communication Module

The goal of this project is to identify the most promising measurement method and strategy for measuring the thickness of grease and to design a sensor module with electronic read-out and communication module. This project has been split into two parts: a sensor implementation and a communication system. This report describes the design and...

An Acoustic Implementation of an Online Sensor Grid for Measuring Grease Deposition in Extraction Channels

The cleaning company "VETkanaal" requested a sensor system that measures the thickness of a grease layer within kitchen extraction ducts independently and is able to send this to an online platform. The goal of this project is to find an acoustic implementation of the sensor and be able to apply it. It appeared that measuring a shift in...

Quality and Cost Modeling Of 3D Stacked ICs

Since the 1960s, the semiconductor industry’s rate of progress has followed by what is commonly known as Moore’s law. In recent years, the traditional approach of downscaling the feature size and increasing the operating frequency of the devices to improve the performance is slowing down due to the reaching of physical limits. Different...

Dilating Pupil for Prosthetic Eyes Based on Electrowetting

The prosthetic eye is created to help people who have lost an eye. The eye itself can only improve the appearance but without any optic function. In order to optimize the appearance, a prosthetic eye with a pupil that can dilate and contract according to the light level, just like the natural eye, is desired. The primary goal of this work is to...

An Electrowetting Valve with Air Channel

In recent years, microfluidic systems are used in various fields. In important component is the valve. In a variety of valve principles, the electrowetting valve promises high reliability, good controllability, low voltage operation and high transmission speed characteristics. The micro-fabrication method to create a chip-level electrowetting...

Easy ID: A Wireless Sensor Package to Measure Human Interaction Features

This thesis proposes a low-cost and small size customized data acquisition sensor badge, called Easy ID, which is specially designed for the Vision Lab Group in TU Delft for their on body data capture during social events. Easy ID is designed based on an open source platform, which provides enough space for future upgrade and extension.<br/>The...
