Robotics
One of the major applications of robotics in the electrical field is in construction. Electrical contractors can use construction layout robots to map out electrical components, such as grids for outlets, conduits, and switches, based on building plans. These robots increase efficiency and accuracy, reducing the need for reworks. They can also assist with surveying, providing precise measurements in less time than manual surveying methods.
While some worry that robots will replace electricians and electrical engineers, others argue that they will simply free up time for these professionals to focus on more complex and skilled tasks. Electrical work often requires tailored designs and site inspections, which robots may struggle with without qualified engineers to guide them. Additionally, fault-finding and other complex tasks will still require skilled workers.
In the short to medium term, electrical engineers are likely to see their productivity boosted by AI and robotics, rather than being replaced by them. Electrical engineers will be needed to design, manufacture, and maintain the infrastructure for AI development. However, as robots become more flexible, durable, and conscious, the potential for them to replace human labour and thinking increases.

Wireless power transfer
Electrical engineering is closely tied to innovation, and wireless power transfer (WPT) is one such innovation that has the potential to revolutionise the way we power electrical devices. WPT eliminates the need for wires and batteries, increasing the mobility, convenience, and safety of electronic devices. This technology can be applied to various fields, including consumer electronics, electric vehicles, medical devices, aerospace, and more.
WPT uses electromagnetic fields to transfer electrical energy from a power source to an electrical device without any physical connectors or wires. The technology consists of a "transmitter" device connected to a power source, which converts the power to a time-varying electromagnetic field. The receiver device, such as a smartphone or electric vehicle, then extracts the power from this field and supplies it to an electrical load. This process is known as inductive coupling, the most widely used wireless power transfer technology.
The efficiency and range of WPT systems vary depending on the technology used. Some systems use magnetic fields, while others use electric fields, microwaves, or lasers. One extension of inductive coupling is resonant inductive coupling, which uses resonance to improve power transfer efficiency over greater distances. This is achieved by tuning the transmitter and receiver coils to the same resonant frequency.
The future of WPT holds exciting possibilities, with ongoing research and development efforts to extend its capabilities. For example, powering IoT devices, industrial machinery, and transferring power over longer distances for space-based solar power systems. Electrical engineers will play a crucial role in designing and improving these technologies, ensuring that WPT becomes a more common method of powering devices in the future.
As the market for electric vehicles (EVs) continues to surge, WPT will likely become even more important. Electrical engineers will be in demand to innovate and improve WPT technologies, ensuring the efficient and effective charging of EVs. Additionally, with the growth of innovation-driven industries, electrical engineers will have diverse career opportunities in sectors such as robotics, consumer electronics, and smart grids.
