	abstract = {Much effort has been put into optimizing the energy-efficiency of wireless
sensor nodes, but existing work exclusively focuses on the transceiver and
the processing unit. Nevertheless, the peripheral energy consumption may
dominate that of the entire node. We introduce the concept of a dynamically
scalable peripheral voltage supply: Even for peripheral devices, a lower
voltage level leads to a lower energy consumption. Each peripheral requires
a different minimum operating voltage, but switching the voltage level
consumes energy as well. We combine theory and practice to present an
algorithm weighing off the benefits of a downscaled voltage level against
the switching overhead, i. e., for calculating an optimal peripheral
voltage schedule. Our approach is capable of self-parameterization and has
been implemented and tested on a prototype, saving up to 47\% of peripheral
energy as compared to existing solutions.},
