Thanks for the link Sabastien
dump the full bridge rectifier for two half bridges.
1) efficiency may double at these low voltages!
2) the common mode noise voltage created by a full bridge currupts the analog front end, getting worse with miniturization due to proximity of the power conversion
Piezo and electrostatic principles are applied for energy harvesting. Piezo will be able to generate more power at least 10 times more than the electrostatic device.Also piezo will have more life time than the other one.
As we unveil EE Times’ 2015 Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. Panelists Dan Armbrust (investment firm Silicon Catalyst), Andrew Kau (venture capital firm Walden International), and Stan Boland (successful serial entrepreneur, former CEO of Neul, Icera) join in the live debate.
