Integrated battery replacement for power harvesting tags


If you are a tag designer, check out this new device that replaces the battery, rectification, and regulation functions of the power supply for use with energy harvesting.  This device, when combined with an energy harvesting source like solar cell, or mechanical source can power a tag perpetually.

Wireless Healthcare Standards Evolving


The Continua Health Alliance is trying to solidify an application standard for interconnected healthcare devices that are both mobile, like pulse oximeters, and fixed like sensors used for remote patient monitoring. These technologies promise to ease the burden of caring for the elderly whether in their own homes or assisted living centers. In the quest [...]

Sensors in the Cloud


Sensor networks with hierarchies and their resultant isolation will eventually give way to the notion that all devices should interoperate with the world, through IP protocols. I’ve advocated this trend for some time, but several news items from Sensors magazine reinforce this: Zigbee and IP and Pedigree Releases Oneview
From an architectural perspective, this [...]

RFID Forecast 2009-2019 Interesting Notes


In a recently released report: RFID Forecasts, Players & Opportunities 2009–2019
I found several thing interesting: (Context warning: this is related primarily to passive technologies.)
1. The total spend is only expected to grow 10% in 2009. Hardly a sign we are on the hockey stick of adoption.
2. Three of Five dollars spent is by Government.
3. Government’s [...]

ZigBee vs WiFi smackdown!


Zigbee the much touted wireless sensor network standard has been around a while now. Yet, it’s adoption has been limited. Already several variants and versions have emerged. Any willing vendor can obtain chipsets and protocol stacks and get started right away. But what always makes or breaks a new standard is how well it [...]

New Zigbee Health and Wellness Profiles


Recently, the Zigbee Alliance released standards for Medical oriented devices to allow standardized interoperability for device functions. Eventually, this should allow worthwhile peer- to peer functionality on the 802.15 network, over and above centralized monitoring applications. I can see this functionality built on Zigbee being very useful in elder care facilities, because of its [...]

Integrated Wifi Module and middleware


You may be interested in this new module from G2 released just last week. It’s the most power efficient, and fully integrated Wifi device available. It’s almost everything you need to build a tag or data collection device except interconnects, sensors, a battery and housing, with all the certifications done. At $22 [...]

Is it time for the RFID hockey stick?


In tech adoption, there is a phase where rapid uptake and expansion occur once maturity has begun and the early adopters have proven the concepts. What I’m seeing at this show, is that passive RFID is very close to that phase. However, there are remaining barriers, and they are no longer in the fundamental technology, [...]

What’s in an acronym – RFID and RTLS


There seems to be confusion in the industry about where these descriptions differ.
RFID is a general description of any system that identifies without line if sight. At a cursory glance, RTLS (Real time location System) seems to add a qualitative presentation and timeliness element to data that is collected by RFID.
But ask yourself [...]
