HP Labs announced the development of a new accelerometer sensor that is The sensors will be relatively cheap to produce in large quantities. It's unclear when or if they'll become common place in future consumer electronics, showing up in smartphones and games consoles for example. One of HP's main goals for the sensors is for them to be used in city-level projects. The company envisions sensing nodes about the size of a pushpin stuck to bridges and buildings to warn of structural strains or weather conditions, and scattered along roadsides to monitor traffic, weather and road conditions.
