Conclusions and Future Work

In order to achieve batteryless operation of low power systems such as wearable devices, energy harvesting has been utilized to enable autonomous operation; however, it is critical to efficiently harvest energy from the surroundings. Furthermore, dynamic voltage scaling plays an important role in reducing the overall power consumption of the device. Both solutions require building a power management unit (PMU) that highly achieves energy-efficient systems with a minimum form factor to suit the wearable applications of the human body. Thus, this work has focused on designing efficient voltage regulators for TEG energy harvesting-based device.
