ENERGY TRANSDUCER
The system embeds an energy transducer with a boost converter to be used with harvesters having an open-circuit voltage (Voc) less than 3.0 V. For harvesters with an opencircuit voltage Voc greater than 3.0 V, the boost converter is optional. It is therefore recommended, whenever possible, to use transducers with an open-circuit voltage greater than 3.0V and an operating voltage of 2.5V to achieve greater energy efficiency and cost effectiveness. The minimum power that the energy transducer must provide is 30 μW.
| Boost converter | Embedded to be used with harvesters with Voc < 3.0V |
| Optional Boost converter | for harversters with Voc > 3.0V |
| Recommended transducer open | Voc_Min = 3.0V |
| Recommended operating voltage | Vope = 2.5V |
| Minimum output power | Pout = 30 μW |
| Efficiency | greater energy efficiency and cost-effectiveness with Voc > 3.0V |
