The document discusses batteryless wireless technology and its advantages over traditional wireless systems that require batteries. Batteryless wireless systems harvest energy from ambient sources like light or radio waves, allowing them to operate indefinitely without maintenance. While initially more expensive than battery-powered alternatives, batteryless wireless systems provide long-term savings through their lack of replacement batteries or energy costs. The document promotes batteryless wireless as a sustainable option for applications where long operational life and lack of maintenance are priorities.
