- Abstract:
- 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.
