Domestic research team has developed the ‘wireless smart sensor’ that does not need battery in the sensor itself.
The development leading role was taken by group research team led by new material engineering dept. professor Jangoong Park, chemical engineering dept. professor Sungyoo Hong, and electrical and computer engineering dept. professor Youngjae Byun of UNIST.
Professor Park’s team has realized wireless smart sensor that can be used in transparent and free form like stickers by joining graphene21 and metal nanowire and creating ‘hybrid transparent electrode element’.
The sensor can be attached to different body parts or skin and be use to sense bio change, such as protein shift, at real time. Even if the form of the sensor changes, it has no problem of sensing the changes in the body. It does not become oxidized even if being exposed in air or heat for a long time. It has excellent flexibility and elasticity as well.
The exterior receiving antenna provides the needed power for the sensor so there is no need for battery. Once the receiving antenna sends out the wave signal, the internal antenna within the sensor reflects the received data.
Also the receiving antenna can be installed on to other devices and use the mobile battery power to send and receive sensor data.
Professor Park said, “We took care of the battery problem which was a stumbling stone in commercializing smart sensor. Also we have provided methods to commercialize the smart sensor and open the door for the next generation to take a step closer to developing wearable devices.
