Sensor Patch: Subgroup: Microcontroller and Communication

This research investigates the feasibility of a sensor patch for newborns. A sensor patch would be a device that is applied to the skin of the newborn. It can monitor the patient's temperature, heart rate, respiration rate, oxygen saturation and asses its general appearance of the skin so that it can check the newborn for jaundice. It should...

The Sensor Patch: Group Energy

The objective of the bachelor graduation project detailed in this thesis is to develop a wireless sensor patch that monitors the health of newborns. The sensor patch replaces the monitoring tasks of nurses during maternity care. The patch measures temperature, heart rate, oxygen saturation and bilirubin. Many babies are born with high bilirubin,...

Geological Research using Electronic Markers: Design of a signal processing system for chipless RFID

In this thesis, the implementation of a passive, chipless, frequency coded RFID detection system for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. Different algorithms are explored...

An atto-Farad resolution closed loop impedance measurement bridge for capacitive sensors

This thesis discusses the theory, circuit design, software design and measurements of an atto-Farad resolution closed-loop impedance measurement bridge circuit for capacitive sensors implemented using commercial off the shelf components.<br/>A lock-in amplifier (LIA) method is used here. The capacitive sensor embedded in an impedance bridge is...

Heartbeat Detection using Infrared Thermometry in the Ear

Heart rate is a key factor in cardiovascular system monitoring and sports science. Some recent commercial applications use sensors in the ear but are faced with motion artifacts which corrupts the signal. In this report, a comprehensive review of heart rate detection methodologies was completed in order to find possible solutions with better...
