Battery-Free IoT Solution

Discovering IoT Solutions with Adamant Orbray's Battery-Free Sensor Network
In order to utilize Machine to Machine (M2M) capabilities where data is exchanged between machines and the Internet of Things (IoT), it is important to collect and store data from various sensors and devices in areas of digital visualization such as:

  • Monitoring
  • Abnormality Detection
  • Analysis
  • Prediction
  • Control

Adamant Namiki offers Battery-Free Sensor Networks using our unique Energy Harvester Device. These Energy Harvesters generate the energy needed to power the sensors and wireless drives for battery-free and maintenance-free sensor network systems.

Sensor Device

By combining our battery-free technology with our wide array of sensors, we can fulfill your demands and needs such as status monitoring, abnormality detection, and the collection and storage of data — all remotely.
Our Energy Harvester has the ability to behave as a sensor on its own.

Wireless Communication

A single motion such as shaking, pushing, or releasing the harvester can generate enough electrical energy to send data via a specified low power radio frequency (2.4GHz, 920MHz, 420MHz, 315MHz) or IR.

*Used a switch type energy harvester as a wireless power source.
*The antenna on the receiving side and the transmission side are installed at a height of 1m.
