Wearable devices, attachable to human body has led to the next generation of electronic devices with the development of the technology in sensor, communication and materials/components such as the improvement of battery life.
However, it is difficult that wireless communication, mainly used for wearable device, allows devices to be micro-sized with ultra-low power and have security system against wireless hacking.
A Korean R&D research institute has developed a low-power on-body human communication technology for wearable device. The technology is able to facilitate fast data transfer and optimise power consumption through narrow band digital transmission. It also enables different devices to build the network and to be operated simultaneously.
The specification of the semiconductor chip employed to this human communication technology meets a world class standard with 1000kbps for transmission speed, lower than 10mW for power consumption.
The technology can be used for identity verification, smart band, smart patch and etc. Currently, the Korean R&D institute demonstrates with local governments to provide senior citizens customised care services through measuring and analysing the daily activities.
Any companies or research institutes in wearable device manufacturing, elderly caring or related service can employ this technology to develop stable and energy-efficient wearable device. Also, the Korean R&D institute is interested in exploring new areas to implement the human communication technology by joint R&D project such as EUREKA and EUROSTARS.
