Projects

EduSat: Kleinsatellit als Chance für Fach-, Semesterübergreifende und interdisziplinäre Lehre
Das Projekt EduSat fördert die intrinsische Motivation der Studierenden, indem es innovative Lehrinhalte in Elektrotechnik und Informatik durch die Entwicklung eines CubeSat vermittelt. Studierende aus verschiedenen Studiengängen arbeiten semester- und fachübergreifend an allen Phasen des Projekts, von der Konzeption bis zum Testen des Satelliten. Das Projekt ist in Primär- und Sekundärmissionen unterteilt, wobei sich die Primärmission auf die On-Board-Avionik (Raumfahrtelektronik) konzentriert und durch die aktive Beteiligung von Studierenden aus Elektrotechnik, Informatik, Mathematik und anderen Fachbereichen der TUHH eine breite Wirkung erzielt.
SatelLight: SatelLight
The SatelLight project addresses the challenges of internal communications within a satellite. Research is being conducted into how LiFi - data transmission via light - can be used to replace cable harnesses and make communications more secure, robust and reliable.
AuRelia: Autonomous and Reliable SCG-Sensor System for Human Space Exploration
The AuRelia project addresses challenges of health sensors for lunar missions with strong sensor autonomy and extremely high reliability. It focuses on SCG (Seismocardiography) sensors and serves as a foundation for further fundamental research on SCG, marking the first investigation into artifact formation on SCG.
SArES: SArES - SCG-Sensorsystem für Artemis II Experiment SpacePatch
SArES is making an important contribution to future SCG sensor systems for monitoring the health of astronauts. In particular, SArES research will focus on local data backup and a hardware, firmware and software system tailored to the Artemis mission as a flight-capable system.
RISA: RISA - Reliability Investigation of Low Power FPGAs for Space Applications
RISA (Reliability Investigation of Low Power FPGAs for Space Applications) is a small payload for the PLUTO technology demonstrator satellite. In particular, RISA tests the suitability of low-power FPGAs for use in space missions and evaluates mechanisms for detecting errors. RISA payload will provide important findings for the reliable use of LP FPGAs in space environments.
BEAT: (Wireless Compose 2) BEAT - Ballistocardiography for Extraterrestrial Applications and Long-Term Missions
The BEAT experiment performed on the ISS is investigating ballistocardiography as a method for inconspicuous and resource-saving long-term monitoring of cardiovascular function.

Past Projects

TRIPLE-nanoAUV: Building access to outer planetary oceans
TRIPLE stands for – Technologies for Rapid Ice Penetration and subglacial Lake Exploration.
REAP: Robuste, energieeffiziente drahtlose Sensornetze für realistische Außeneinsatzszenarien durch Adaption von Betriebs-Parametern (DFG: BU 3282/2-1)
Monitoring the changing environmental conditions allows to benefit from the systems dynamics. Realistic models for energy and reliability will be derived from these measurements. Combined with the knowledge about the characteristics of the nodes in the network, this information can, e.g., be used for routing decisions, task scheduling, and processing within the network.
PotatoNet: Outdoor Testbed zur Evaluation drahtloser Sensornetze unter realen Umgebungsbedingungen
Das PotatoNet ist ein Versuchsaufbau, welcher es erlaubt Hardware und Routingprotokolle von selbstentwickelten Sensorknoten unter realen, zum Teil extremen, Betriebsbedingungen zu untersuchen.
INGA: Inexpensive Node for General Applications
INGA is an open source wireless sensor node for anything. INGA was developed at IBR (TU Braunschweig) as Inexpensive Node for General Applications and is used in numerous projects. The motivation to develop INGA was driven by the need for a reasonable, cheap and expandable node for several use cases.
5GSatOpt: Building access to outer planetary oceans
Das Projekt 5GSatOpt behandelt die Integration von Satellitenkonstellationen kleiner Satelliten mit 5G.

Efficient online Compression of BCG Data

Typ: Forschungsprojekt
Status: abgeschlossen
Supervisors: Ulf Kulau
Project: Wireless Compose 2
Development and investigation of an efficient online data compression on a resource constrained FPGA device for BCG data

Towards a resource efficient system for ecoacoustic recording

Typ: Bachelorarbeit
Status: abgeschlossen
Supervisors: Ulf Kulau
Bearbeiter: Jan Lueken (abgegeben: 23. Sep 2022)
In this thesis, the possibilities for increasing the efficiency of ecoacoustic systems are investigated. For this purpose, a prototype ecoacoustic sensor system is built and data is collected and evaluated in a field test

Evaluation von Undervolting auf LP FPGAs

Typ: Masterarbeit
Status: abgeschlossen
Supervisors: Ulf Kulau
Bearbeiter: Lucas Bublitz (abgegeben: 30. Oct 2022)
In dieser Arbeit soll grundlegend untersucht werden, in weit es möglich ist Low Power FPGAs unterhalb ihrer spezifizierten Spannung betreiben zu können. Um dies eingehend untersuchen zu können, muss eine Testbench entwickelt und evaluiert werden, welche hohe Präzision und Robustheit gegenüber bspw. Temperatureinflüssen erfüllen muss. Eine abschließende Messkampagne soll erste Ergebnisse bezüglich der Machbarkeit von Undervolting auf LP FPGAs zeigen.

Integration and Evaluation of an Online BCG Compression Core into a RISC-V Softcore

Typ: Masterarbeit
Status: abgeschlossen
Supervisors: Ulf Kulau
A significant advantage of softcores is that one can implement and connect one's own hardware accelerators alongside them. In this thesis this will be done with a compression kernel, which allows the online compression of BCG data and is integrated into a Risc-V softcore. A final evaluation will reveal advantages and disadvantages.

Anomaly Detection from BCG Signal With Artificial Intelligence

Typ: Forschungsprojekt
Status: abgeschlossen
Supervisors: Ulf Kulau
Project: PotatoNet
Recent advancement in artificial intelligence shows promises to detect anomaly from continuous data accurately and reliably without any supervision. Thus, in this work, we will do research on developing a deep learn- ing model to detect anomaly from continuous BCG data.

Energy Harvesting für Unterwasser-Sensoren und Nutzung des Energiesignals zur Bestimmung von Strömungsparametern

Typ: Bachelorarbeit
Status: abgeschlossen
Supervisors: Ulf Kulau
In dieser Arbeit soll ein Energy-Harvesting System entwickelt werden, welches aus der Wellenbewegung Energie für den Betrieb von Unterwasser-Sensorik erzeugt. Dabei soll ferner untersucht werden, in wie weit unter Berücksichtigung der Verluste beim Harvesting auf mögliche Wellenbewegungen rückgeschlossen werden kann.

Eingebettete KI zur sensornahen Auswertung von BCG Signalen

Typ: Masterarbeit
Status: abgeschlossen
Supervisors: Ulf Kulau
In dieser Arbeit soll untersucht werden, wie BCG und SCG Signale auf einem ressourcenbeschränkten System mittel eingebetteter KI ausgewertet werden können. Hierzu sollen zunächst existierende Frameworks auf ihre Eignung geprüft werden. Ein neuronales Netz soll entworfen und mit existierenden Daten trainiert werden. Eine abschließende Evaluation auf einm Mikrocontroller soll die Machbarkeit demonstrieren.

Lightweight Testcore for Hardware Modules of LP FPGAs

Typ: Forschungsprojekt
Status: abgeschlossen
Supervisors: Ulf Kulau
In this project, we focus on developing a lightweight hardware Testcore for FPGAs that we can utilize to detect these SEUs/bit-flips regardless of FPGA resource conditions and perform a blind scrubbing if an error is detected.

Entwicklung einer effizienten und zuverlässigen LiFi-Kommunikation für Kleinstsensoren

Typ: Masterarbeit
Status: abgeschlossen
Supervisors: Ulf Kulau, Lucas Bublitz
In dieser Arbeit soll untersucht werden, wie mittels LiFi Kommunikation Daten drahtlos von einem hoch-miniaturisierten Sensorsystem zuverlässig und effizient an eine Datensenke übermittelt werden können.

Implementation and Evaluation of an efficient chest-worn PPG Sensor

Typ: Bachelorarbeit
Status: abgeschlossen
Supervisors: Ulf Kulau
Among other things, PPG is a good reference method for reliably detecting heartbeat and heart rate. For this purpose, there are a number of possible optical frotends and biosensor modules, which will be miniaturized, implemented on a pcb and evaluated in detail.
