Emergency exit lights in public buildings are necessary for safety and evacuation. International safety standards require such lighting in many public places, like airports, schools, malls, hospitals, and other spaces, to prevent human casualties in emergencies. Emergency exit lights have become an essential part of casualty reduction projects. They can pose several application problems, including fire safety concerns. The issue of providing a safe way and operating emergency exit lights along one side of a long path arises during an emergency. Many studies in this field consider the case in which emergency exit lights’ battery or main power fails. Power failures in dangerous situations such as fires or terrorist attacks make it difficult for people to escape. The lighting in open areas and stairwells during an emergency should be at least 2 lux. This work proposes an innovative technique for wirelessly powering emergency lights using microwave energy. Specifically, the study designed and fabricated a new wirelessly powered emergency lighting prototype. This prototype’s wireless power transfer (WPT) base comprises an RF/DC converter circuit and an RF microwave transmitter station. The device can harvest RF microwave energy to energize the emergency light. This research aimed to develop a compact device that captures maximum RF strength to power emergency lights. As a prototype, the proposed device was designed to provide sufficient microwave energy to power an emergency light at 3 W over a 62 m distance.

Wireless Power Collecting (WPC) present the future in powering and energizing intelligent Internet of Things (IoT) electronics devices. This chapter studies and utilizes a circuit to powering wirelessly IoT devices. The WPC offer a best technique to help researchers and engineers of modern societies to build cell blocks. The concept is to energy any IoT devices and sensors wirelessly from Radio Frequency (RF) power strength in the same areas that may be hard to achieve or potentially hazardous. We implemented the RF harvesting technology with IoT devices to increase the efficiency of sensors. The idea of this system is to power up and self-energize any IoT sensors wirelessly. This work studies two different topologies of a rectangular patch antenna and different RF harvesting circuit voltage multiplier configurations using a microwave power station as the input RF source. This work aims to utilize the wireless power transmission technique in the smart house solution. The proposed prototype gets all technical parameters to generate enough electricity to power up the bulbs 5 W wirelessly at a gap distance around a five meters. Finally, we test the RF rectifier circuit coupled with a twin patch antenna that can self-energize the bulb, eventually devices work without batteries.

A significant challenge for the military lab is to reduce the weight of a combatant’s battery on the battlefield. Soldiers use electronic devices powered by wearable batteries in landings, operational combat with the enemy, and defensive exercises. Soldiers should always fully charge their wearable batteries before carrying them. The average weight of the battery is approximately 20 kilograms. During military operations, fighters have numerous electronic devices, such as night-vision goggles, headphones, LMR, navigation systems, VHF radios, and sensors. There is a high probability that fighters will lose their lives if the battery they take is uncharged or empty. Many research studies have tried to increase fighting time and maintain soldier life and links based on these devices. In this work, a wireless power transmission system with an RF microwave station and RF/DC converter circuit incorporated into a bulletproof vest will be designed. This system can harvest RF microwave energy to recharge or energize the wearable battery during a military operation. The challenge here is to develop a compact device that can capture the maximum RF strength to charge batteries carried by soldiers. The proposed device therefore considers all parameters to provide sufficient energy to power a computer at 13 watts. The strength of the RF power varies with the distance between the microwave power station Pin = 100 W and the receiver circuit.
