NGK, Exeger, TACHIBANA ELECTRONC SOLUTIONS and Semtech Develop a Maintenance-Free Indoor/Outdoor Position Tracker that is High-Precision, Ultra-thin and Compact

NGK INSULATORS, LTD., Exeger Operations AB, TACHIBANA ELECTRONIC SOLUTIONS CO., LTD., and Semtech Corporation, have developed a maintenance-free indoor/outdoor position tracker that is high-precision, ultra-thin and compact, together.

NGK INSULATORS, LTD. (hereinafter “NGK”), Exeger Operations AB (Stockholm, Sweden; CEO & Founder: Giovanni Fili; hereinafter “Exeger”), TACHIBANA ELECTRONIC SOLUTIONS CO., LTD. (Minato-ku, Tokyo; President: Toshimichi Shibata; hereinafter “TACHIBANA ELECTRONIC SOLUTIONS”), and Semtech Corporation (California, USA; President and CEO: Mohan Maheswaran; hereinafter “Semtech”), have developed a maintenance-free indoor/outdoor position tracker that is high-precision, ultra-thin and compact, together.

The indoor/outdoor position tracker developed by the four companies has a power supply system that uses NGK's ultra-thin and compact “EnerCera®” (*1) lithium-ion rechargeable battery and Exeger's “Powerfoyle” (*2) solar cell that efficiently generates electricity both indoors and outdoors. It operates an ultra-thin board based on the “Zero Carbon LoRa® Evaluation Board” (*3) circuit board sold by TACHIBANA ELECTRONIC SOLUTIONS using Semtech's LoRa® (*4) connectivity IC and the “LoRa Edge™ LR1110” (*5).

The tracker is maintenance-free and can be used both indoors and outdoors without battery replacement or charging (*6) thanks to energy harvesting technology, which converts light such as indoor light and sunlight into electricity. In addition to providing highly accurate location information, the tracker enables record temperature, humidity and shock, and smooth data analysis by transmitting collected data to the Cloud via LoRa®. Because of its thinness of only 6 mm, the tracker can be used in wearable devices and logistics trackers as an independent IoT device equipped with a series of functions from location information acquisition to data transmission, and it will contribute to improved operational efficiency and labor savings by visualizing the movement of people and goods.

In the future, through experimentation and evaluation, the four companies plan to examine a solution business that utilizes location information, such as systems to protect children and the elderly, manage the activities of office personnel, and analyzing the movement lines of people in stores, factories, and other specific locations. As the indoor/outdoor position tracker can record not only location information but also temperature, humidity, and impact, the four companies additionally plan to develop applications in a wide range of fields going forward, such as temperature and humidity control of goods and containers. They intend to continue to leverage their knowledge in accelerating the global shift to IoT, promoting the social implementation of IoT devices in society, for which they expect growing demand.
