A nanoscale rectifier and nanoantenna are two examples of a type of device that transform electromagnetic radiation into electrical energy. The words “rectifier” and “antenna” are combined to form the word “rectenna”.
Usually made up of a variety of tiny antennas, nanoscale rectennas are intended to effectively absorb electromagnetic radiation at a variety of frequencies, from radio waves to visible light.
An electrical current is then created from the absorbed radiation using a rectifying diode or another similar device.
Applications for nanoscale rectennas include energy harvesting for autonomous sensors and other small electronic devices, as well as the creation of wireless power transfer networks.
In addition, they might be useful in photovoltaic systems and other applications that need for the effective conversion of electromagnetic radiation into electrical energy.
The Global Nanoscale Rectenna Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Growing interest in connecting existing macroscale networks to nanoscale devices to create the Internet of Nano-Things (IoNT) has been sparked by recent advancements in nanoscale sensors.
For data processing and exchange in the monitoring system in an IoNT system, a number of nanosensors with basic computing and communication capabilities can be dispersed throughout the environment.
The ability of nanosensors to communicate with one another can increase their capacity to carry out some more difficult jobs. The IoNT can be used in healthcare, defence, and environmental applications thanks to the connected nanosensor network.
A model for nano-rectenna energy harvesting is created. A nano-antenna and an ultra-high-speed rectifying diode combined as a nano-rectenna gather energy.
This device can be used to power nanosensors using a portion of the terahertz (THz) information signal without the need for any other external energy source in the system.
Nano-rectennas’ broadband features allow them to generate direct current (DC) electricity from THz to optical frequency inputs. The authors compare the power required for nanosensors to communicate in the THz band to the output power generated by the nano-rectenna.
