BAN! Not an explosion, but the abbreviation of the new concept "Body Area Network" proposed by the Dutch research institute IMEC. This technology is basically a set of exclusive IP for the sensors installed on the human body, which is installed on the mobile phone (displayed The mobile phone is a Google G1 Android phone.) The receiver receives the message and collects the health of the human body through the mobile phone. In the event of an emergency, the message can be transmitted to the remote medical staff via the 3G or Wi-Fi network of the mobile phone. Inform them to go to the patient's location quickly.
Wireless applications like this are not pioneering, but most similar human sensing systems use general-purpose technologies such as ZigBee or Bluetooth, but IMEC believes that if Bluetooth is used, the power of the system for the human body can only be supplied for one day; So they use the nRF24L01 + Radio from Nordic Semiconductor (NORDIC SEMICONDUCTOR), a 2.4GHz non-universal standard RF chip that allows the system to maintain 7 days of endurance.
The problem of IMEC is actually the problem that most general wireless standards want to enter into medical and medical communication standards. Because of the need to load more applications, the general standards cannot be adjusted for specific needs, resulting in more difficult power consumption reduction; One point is the mutual interference between radio frequency and medical instruments. This is especially the most taboo for medical equipment. If radio frequency affects the application of medical devices such as heart rate adjusters, it will not be worth the loss.
The purpose of this system is to concentrate human body information on the mobile phone as a unified transmission platform through a mobile phone with almost one hand, without collecting additional data through an exclusive device, so that the medical and medical monitoring system is more integrated into life.
