Battery-Less Radio Circuit

At the International Solid State Circuit Conference,

imec and Holst Centre report a 2.4GHz/915MHz wake-up receiver which consumes only 51µW power. This record low power achievement opens the door to battery-less or energy-harvesting based radios for a wide range of applications including long-range RFID and wireless sensor nodes for logistics, smart buildings, healthcare etc.

Today’s battery-operated wireless communication systems consume a lot of power at times when the radio does not have to transmit or receive data. This means that most of their time Bluetooth or WLAN radios on mobile phones are taking energy from the battery without adding functionality. Imec and Holst Centre’s wake-up receiver with ultra-low power consumption and fast response time can be put in parallel with the conventional radio to switch it on when data needs to received or transmitted.

  1. Battery-less portable products will be much more popular once WiMax kicks in. That's the next big thing in wireless communications. I guess it's up to the telecom towers manufacturers now.
