"At a Fujitsu technology expo in Tokyo this week the company is showing off the prototype tags. They contain various sensors commonly found in smartphones such as accelerometers, barometers, gyroscopes and microphones. They can also house heart rate sensors and GPS modules.
"The sensors are being housed in stand-alone tags to better promote IoT apps, according to Fujitsu.
“Algorithms that are part of the platform analyze the sensor data and can automatically send alerts to supervisors when a patient has fallen down, for instance, or if a worker is experiencing a heavy physical load and heat while working on a tower for high-voltage cables.”
