These report blood glucose levels every 5 minutes, thanks to a small radio transmitter attached to a fine sensor wire that runs under the skin (the wire is replaced weekly, the transmitter every six months.

#Green Microchips Created on Cellulose Nanofibril Paper In September 2007, while leafing through his copy of IEEE Spectrum, Zhenqiang"Jack"Ma, an engineer at the University of Wisconsin-Madison whose research focus is microwave electronics,
each cell phone contains chips made of poisonous gallium arsenide (Gaas. In the 26 may issue of Nature Communications, Ma and his colleague, materials scientist Shaoqin arahgong, plus collaborators at UW-Madison and the Madison-based U s. Dept of agriculture Forest Products
Laboratory (FPL) published research describing a technique for making biodegradable semiconductor chips out of wood.
What more, they demonstrated that microwave transmitter and receiver chips made this way perform as well as their silicon or Gaas counterparts. ctually,

To create the green chips, the researchers started out with silicon or Gaas devices sitting atop substrates made of the same material.
Using paper substrates would allow a reduction in the amount of Gaas used in chips by a factor of 3000,
which would make chips conform to the pollution standards for arsenic set by the U s. Environmental protection agency.

From the population of neurons tapped by those electrodes, the researchers could distinguish cells whose activity coded for the location that Sorto wanted to reach, movement trajectories,

Chips built for phones, tablets and even some laptops are designed to use small enough amounts of power than they can dissipate heat without blowing a bunch of air all over everything.

#Cheaper Sensors Will Fuel The Age Of Smart Everything For better or worse, we are about the enter the age of smart everything.
the fact is that sensors, the tiny devices that fuel the Internet of things are getting smaller and cheaper all the time.
The Internet of things in actuality involves a network of smart sensors collecting data. As the sensors grow ever cheaper,
and the network grows ever larger, the more data we can collect to make ever more intelligent decisions (at least in theory).
On The Edge Of A major Shift Nils Herzberg, global co-lead for Iot at SAP says the beauty of sensors that they bring real-time data to applications. ustomers run applications for business critical processes,
He says when sensors provide real-time information, customers can make better decisions, rather than using guess work.
and cost of sensor technologies, says James Bailey, managing director of the mobility practice at Accenture. ur perspective is that cost of both the sensors
and devices is approaching free and the size is approaching invisible. Our perspective is literally everything will have IOT technology at some point,
What he means that the same sensor data may used differently, depending on the industry. t driven by the business case,
Sensors can feed a company data to make highly inefficient processes much more efficient, but SAP Herzberg says the proliferation of that data has become so massive that companies are overwhelmed
That evolution takes a certain critical mass of sensors in the network and software that can begin to make better use of the data the sensors are collecting.
For now he says SAP is one of a number of companies including IBM, Microsoft and countless startups working on making better predictions.
once you have been able to collect the data from a sensors, you can begin to build increasingly complex sets of predictions. ou can start modeling
Sensors could let the system know a ship hadn docked yet and communicate this to truckers before they drive into the port area.
Moving To Smart Everything Sensors are not just the domain of industry though. Our phones are full of sensors from the GPS to the accelerometer to the compass,
all of them feeding data to apps and to the cloud. So is that Apple Watch,
hey developed a smart employee badge with a microphone, accelerometer, bluetooth connection and other tools typically found in a smart phone.
