This technology is a highly sensitive, ultra-low power wake-up receiver that consumes 5× less power and offers 10× greater sensitivity than state-of-the-art receiver architectures, enabling always-on wireless devices with dramatically extended battery life.
Wireless monitoring systems for warehouse inventory, smart homes, healthcare, agriculture, and infrastructure utilize electronic systems that spend most of their lifetime in a low-power “sleep” state while continuously waiting for a wireless wake-up signal to complete a desired operation. Because wake-up receivers remain active even when the rest of the system is powered down, they are often the primary source of power consumption, limiting battery life and increasing maintenance requirements. Conventional wake-up receivers also struggle to detect weak signals in noisy environments, reducing communication range and reliability. These challenges have limited the widespread use of autonomous, battery-powered and energy-harvesting wireless sensing systems.
This technology is an ultra-low power, high-sensitivity wake-up receiver that significantly improves both energy efficiency and signal detection, enabling autonomous, long-lasting wireless monitoring devices. The receiver employs an optimized RF-matching network to receive the wake-up signal with higher quality. Incoming signals are processed through a cascade of single stage self-mixer circuits to improve energy detection and selectivity to interference with minimal power consumption. Compared with state-of-the-art wake-up receiver architectures, the technology delivers 5× lower power consumption and 10× greater sensitivity, enabling longer battery life, increased communication range, and more reliable wireless operation.
This technology has been demonstrated in a compact hardware prototype under both ideal and high-interference operating conditions
