HaiLa Technologies, a fabless semiconductor and software company focusing on hyper power-efficient wireless communications system-on-chip (SoC) solutions for IoT devices, and e-peas Semiconductor, an industry-leading provider of energy harvesting and processing solutions, have collaborated to show the path to extreme long-life energy storage for Wi-Fi connected wireless sensors. Solutions based on extreme low-power RF and highly efficient power management ICs fulfill a key requirement across multiple applications to reduce and eliminate reliance on standard batteries, both to mitigate sensor network operating costs and environmental waste.
The HaiLa BSC2000 RF Evaluation Chip is the first monolithic analog and digital implementation of HaiLa’s passive backscatter technology adapted to Wi-Fi RF bands. Supporting an SPI interface, the chip brings seamless connectivity to a wide range of IoT devices, such as multi-channel temperature and humidity sensors, that offers a new paradigm in low-power wireless communications. In addition to reducing and eliminating disposable batteries, through repurposing existing Wi-Fi infrastructure HaiLa’s technology paves the way for brownfield sensor deployments, further driving down costs.
Part of the Ambient Energy Managers (AEM) portfolio, the e-peas AEM10941 is an integrated energy management circuit that extracts DC power from up to 7 photovoltaic cell elements to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. AEM10941 PMIC for photovoltaic energy harvester allows battery lifetime extension and ultimately eliminates the disposable battery energy storage element in a large range of wireless applications.
“Leveraging the e-peas team’s deep expertise in PMICs, we’ve been able to demonstrate an energy-harvested power source for Wi-Fi-based sensor connectivity,” said Patricia Bower, VP Product Management, HaiLa Technologies, Inc. “This is a critical step forward towards HaiLa’s mission to enable sustainable scaling of IoT on Wi-Fi and we’re excited to show the joint solution at Sensors Converge.”
“The close collaboration with HaiLa’s team to showcase the power of our combined technologies demonstrates new possibilities to run autonomous Wi-Fi devices free of disposable battery and maintenance requirements,” said Christian Ferrier, Chief Marketing Officer, e-peas S.A. “We're excited to contribute of the new era of new Wi-Fi devices powered by energy harvesting.”
HaiLa’s passive backscatter foundational technology is protocol-agnostic. As the most common wireless local area network (WLAN) technology in residential, enterprise and industrial environments globally, HaiLa has focused its first adaptation on Wi-Fi as a key infrastructure enabler for IoT deployments.
