(mentor) Degree granting institution Delft University of Technology Programme Electrical Engineering | Embedded Systems Date 2023-09-20 Abstract The averse reaction of lithium batteries inspired researchers to look for alternat-ives for energy storage in electronics. Battery-free or intermittent devices intro-duce a new paradigm with their own specific problems about power, state track-ing, timing and communication. We implemented the battery-free paradigm inthe Thread protocol, utilizing the specific characteristics of End Devices in themesh network to reduce power consumption. The intermittent implementationis fulfilled without changing the behaviour of the protocol, making the devicefully compatible without other devices being aware of the intermittent opera-tion. During tests four implementations are tested, completely naive, semi naivewith simple power improvements, Sleepy End Device operating intermittentlyand a Synchronised Sleepy End Device operating intermittently. The results ofthe power measurements are used to determine the feasability of four use cases.The intermittently operating Sleepy End Device is out performing the Naiveand Semi Naive implementation.
