Over the past four years, the number of accidents and deaths on the hiking trail has been increasing. In fact, it is frequent for the rescue team to find the location of the climbing victims. To overcome these problems, five students of the Sepuluh Nopember Institute of Technology (ITS) initiated the SACKER, Smart Jacket for Hiker. Talia Kamil, the team leader revealed that the SACKER is a jacket equipped with a Global Positioning System (GPS) component and a pulse sensor that functions to detect the location and condition of the climbers. The two components were chosen with the aim of minimizing search time in case of missing climbers.
Talia added that the way the GPS component on the SACKER works is that a sender of location signals from climbers. While the pulse sensor component itself is a heart rate sensor that is connected to an indicator light to determine the condition of the climber's heart rate. The light will turn on if the climber's heart rate is above 90bpm. In addition to knowing each other's condition, Talia added, the light is also useful to facilitate the search for climbing victims when they get lost, even at night. Later, data on the location and condition of climbers will be sent with a communication module which will be displayed on the monitor at the registration post. According to Talia, previously there have been similar ideas related to this research, including life vests and location tracking gloves. The difference is that the innovation is equipped with GPS and pulse sensors which are then packaged in a jacket.
Thanks to this brilliant idea, their team won a silver medal in the International Invention Competition for Young Moslem Scientists (IICYMS) 2021 by carryinyg the title SACKER (Smart Jacket for Hiker): GPS and Pulse Sensor – Based Smart Jacket to Monitoring Track and Condition of Hiker.
