Research question
Ø  Body energy harvesters produce small power at low voltages.
The low voltage converters have not been adapted well so far.
This research is looking for methods to improve efficiency and
supply energy for power hungry sensor nodes.
Methods/Results
Ø  Designing optimum and architectures in system level, and use
of ultra-low power blocks in circuit level. 50% efficiency has
been achieved for 20mV harvested voltage up to now.
