Ultrasound for Data Transfers from Deep Implants: an Experimental Comparison Between Binary-Frequency-Shift-Keying and On-Off-Keying with Backscatter Modulation

Implantable devices need to communicate information to the outside world. For deep-seated miniaturized implants ultrasound communication can be favourable. However, implants need to operate during movement, and the selected communication scheme should be assessed accordingly. In this work, we implemented a simple protocol to transfer data...

Two for the price of one: communication efficient and privacy-preserving distributed average consensus using quantization

Both communication overhead and privacy are main concerns in designing distributed computing algorithms. It is very challenging to address them simultaneously as encryption methods required for privacy-preservation often incur high communication costs. In this paper, we argue that there is a fundamental link between communication efficiency...

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...

Wireless Indoor Climate Sensor: Wireless Communication at Ultra Low Power

The required product is a wireless indoor climate sensor. It is an autonomous sensor that transmits several parameters concerning its environment wirelessly. The product will be used to demonstrate a number of energy efficient sensors. The electronic instrumentation department at Delft University of Technology developed these sensors in...

Radio Wave Propagation in Metal Train Compartments

Wireless sensor networks are being deployed extensively to collect sensory data in various environments under different conditions. A wireless sensor network consists of multiple nodes, each with the ability to communicate using radio waves. The characteristics of the radio link between nodes are largely influenced by their environment. For...
