Jennic Demonstrates JN5148, Ultra Low-Power ZigBee Based Transmissions from 100µJ of Energy Harvested from an Electro-Mechanical Switch

The demonstrator shows how a single switch press is all that is required to enable the JN5148 to carry out system startup and initialisation, followed by a succession of packet transmissions to increase the probability of packet delivery to the receiver. Jennic previously announced a series of energy harvesting technology demonstrators utilising thermal, vibrational, RF and solar energy harvesting techniques to power end devices in a wireless sensor network. Jennic’s engineers ensured sufficient energy was left over for a minimum of three packet transmissions to increase the probability of packet delivery to the receiver. The JN5148 totally hit the mark, consuming what in essence equates to an average of 7mA at 2volts for 7ms, the 100µJ budget.”
This latest demonstrator will find particular interest in application of Home Automation (HA) and Commercial Building Automation (CBA) lighting solutions, where wireless, battery-less light switches will control the lighting within the building, minimising the costs associated with cable installation and maintenance. It also links directly with ZigBee’s Green Power standardisation efforts for the integration of wireless, battery-less light switches with ZigBee HA networks…
