GreenPeak Battery-Free Wireless Communication Devices

GreenPeak Technologies recently introduced new products for ultra-low-power wireless sense and control networks. GreenPeak’s new wireless communication devices leverage three key technologies that enable it to operate in a battery-free environment without cabling. The first is an ultra-low-power wireless transceiver and sensor interface design with efficient power-up and power-down modes that dramatically reduce power consumption. Second is an energy harvesting interface that enables the modules to utilize power provided by e.g. external solar, electromagnetic, and piezo-electric transducers. Third is a mesh technology that enables designers to create extended sensor networks without the need for battery-powered or cabled routing nodes. This innovative mesh technology is also self-forming and self-healing, making it easy and inexpensive to install.

GreenPeak is initially offering its low-power communication technology as the ‘Lime CM-08′ module, a tiny 5 cm² (less than one square inch) electronic component that OEM customers can integrate into their products. The tiny module functions as a stand-alone communication system, integrating a transmitter/receiver, antenna, and low-power mesh network software on a single device. The module also features a transmit power amplifier that delivers four times the transmission range of non-amplified products with less than 1% impact on energy consumption. The module’s software can be configured to manage the power of different types of energy harvesting devices. OEMs can also add their own applications to the module, thereby eliminating the need for an external processor and lowering total system cost.

GreenPeak devices can accommodate a variety of energy harvesting devices over a broad range, from the dripping energy of solar cells, to the energy bursts from piezo-electric torsion or electromagnetic fields. GreenPeak has developed on-board power management circuits that will monitor the state of the energy harvesters and take appropriate actions to optimize the available energy. This allows the GreenPeak devices to operate in a battery-free environment in a reliable way.

GreenPeak has created a low-power, self-forming and self-healing mesh technology, which enables wireless devices to build a reliable and efficient communication chain. Each device in the GreenPeak network, utilizing GreenPeak’s integrated mesh software, can act as a repeater for other wireless devices, thereby enabling the network to span larger distances. Unlike competitive mesh solutions, which require battery power or cabling for the main routing nodes, GreenPeak networks utilize smart power-up/power-down and synchronization techniques that enable all mesh nodes to operate in a low-power mode without a battery or power cabling.

GreenPeak is fully committed to development based on open industry standards. The GreenPeak technology is based on the IEEE 802.15.4 wireless network standard and supports the open global standards of the ZigBee Alliance.

The suggested retail price for the GreenPeak Lime module (CM-08) is $ 21 (volume 100K). The suggested retail price for the Starter Kit is $ 1,390 and $ 6,950 for the Development Suite.
