Autonomous sensor systems

Contact: Kofi Makinwa

Sensor systems are used for measuring, monitoring and control. Autonomous sensor systems are sensor systems in which distributed sensor nodes contain local signal and data pre-processing capabilities. Thus, self-testing, auto-calibration, filtering, data compression, etc., within sensor nodes without or with very limited external intervention is crucial. In many applications, wiring is not possible, unreliable or undesirable, which makes the powering of sensors a major issue and calls for ultra-low power electronics and smart design at all levels in the system.

In IoT applications, sensors operate in a network. Limited power resources favor power-efficient communications. Sensors can communicate only with neighboring nodes, creating a dynamic and complex network that relies on self-organizing and self-healing capabilities.

In biomedical applications, the sensors need to be miniaturized and packaged to be bio-compatible or implantable, as e.g. with smart (multi-modal) catheters or electroceuticals, which combine sensing, local data processing, and actuation.

In other applications (autonomous driving or flying enabled by a variety of radar sensors distributed over many nodes), the focus is on robustness and reliability in view of a very dynamic network, and optimal fusion of different sources of information. With TUE we collaborate on a program to realize a low-frequency radio telescope in space using a swarm of nano-satellites (OLFAR). Emerging technologies such as neuromorphic computing and structured data science are expected to play an important role in future.

History

Low-frequency distributed radio telescope in space

Below 15 MHz, the ionosphere blocks EM signals from the sky. Therefore, can we design a radio telescope in space, using a swarm of inexpensive nano-satellites? Accurate localization and clock recovery is important.
