Demand-Driven Technology

A variety of mobile devices that utilize Global Positioning Systems (GPS) and other outdoor location detection services have been produced in recent years. However, GPS operation is often spotty or non-existent indoors, driving the demand for better performance. As a result, several new positioning methods are currently being researched, including broadcasting GPS signals indoors or diverting radio waves transmitted from wireless LAN base stations.

In response to this burgeoning market need, ROHM, Ritsumeikan University and ISID co-developed Guidepost Cell technology, which utilizes advanced location detection and energy harvesting methods to enable an expected positional accuracy within 1 meter (3'), while requiring no external power source for operation.

Key Guidepost Cell Advantages

Dye-sensitized Solar Cell (DSC)

Key Features

Applications

Indoor power sources for low-power electronic devices such as wall clocks and calculators as well as next-generation systems such as indoor sensor networks.
