Optical Wake-up from Power-off State for Autonomous Optical Sensor Nodes
[article]
2020
arXiv
pre-print
Preserved Fulltext
In this study, we propose a novel approach of an optical wake-up for autonomous sensor nodes, which employs a solar cell as a wake-up signal detector. ...
Wireless sensor nodes spend most of their time in standby mode and wake up periodically to send the measurement data. ...
Thus, no power for keeping a microcontroller of a wireless sensor in standby mode is required. ...

Our wake-up receiver consists of two parts: a low power passive circuit connected to a wake-up chip microcontroller and an active micro-electromechanical system (MEMS) microphone that receives the acoustic ...
The receiver contains a low power wake-up module that reacts to an addressable acoustic 20-kHz sound signal that controls home devices that are connected to it. ...
Amir Bannoura and Fabian Höflinger designed, developed and tested the functionality of the wake-up receiver. ...

In [7], a 695 pW standby power optical wake-up receiver for wireless sensor nodes is introduced. The receiver consumes 695 pW in standby mode and in active mode 140 pJ/bit at 91 bps. ...
To significantly reduce, or eliminate completely, the energy waste caused by the standby (idle) mode of wireless sensor nodes, we propose a novel on-demand wake-up system, which allows the nodes to be ...
Wake-up radios are small and low-or no-power devices that activate the wireless sensor nodes when an external wake-up call occurs. ...
