Textile Rectenna for RF Energy Harvesting [PDF]
2021 15th European Conference on Antennas and Propagation (EuCAP), 2021 Wearable devices are part of many people’s lives, however the batteries they need are a major limitation. In order to solve this problem, an energy harvesting system was studied and implemented, to replace the battery usage and thus enhance the device portability.

High gain isotropic rectenna [PDF]
2017 IEEE Wireless Power Transfer Conference (WPTC), 2017 This paper introduces an original strategy to step up the capacity of ambient RF energy harvesters. The low rectification efficiency that comes from weak input power is enhanced through high gain antenna arrays that push the circuit to operate in a more efficient state.
