Core topic ULP sensor systems
The Internet of Things has so far been difficult or impossible to harness for many applications due to a lack of suitable energy supply. Rotating machine parts, for example, cannot usually be supplied with wire-based energy, which is why batteries with limited energy resources are used there. To still be able to connect and monitor these parts over long periods of time, energy-efficient sensor systems are needed.
More challenging are applications where batteries are not changeable, such as moulded or widely distributed sensors in road construction or agriculture, and sensors in hazardous areas such as parts under high voltage. Even more demanding are solutions to be developed without batteries for ecological or cost reasons. There, energy-autonomous passive sensor systems are necessary, which are supplied with energy via RFID, for example, as in smart food packaging or digital rapid tests.
But the sensors available for the development of new IoT applications are mostly not energy-optimised and need energy which does not contribute to the function, such as constantly running clock generators or inefficient interfaces.
We research and develop ultra-low-power (ULP) sensor systems that require very little power and have integrated energy management components.
In addition to classical ULP circuit techniques such as clock gating, we are exploring the use of energy storage and converters as well as central control of the energy flow. We develop models as well as generic and automated modelling methods for the energy flow in ULP sensor systems.
