FHE

Introducing the World’s First Practical FHE Device!

Achieving a thin, lightweight design with an impressive 5-month operational lifespan, this device makes measurement possible in previously inaccessible locations and scenarios. Utilizing printed electronics technology, it prints circuits only where needed, without the use of water or chemical solutions, and employs low-cost equipment. This results in minimal manufacturing resource consumption, contributing significantly to SDGs (Sustainable Development Goals). We aim to transition from sustainable electronics to a circular economy. We also offer contract development services for various applications leveraging our printed electronics technology. Please feel free to inquire.

We’ve overcome the limitations of conventional large, heavy, and short-lived sensors. By combining FHE technology—which mounts sensor ICs onto light, thin, flexible substrates—with optimized firmware for power management, we’ve achieved thin, lightweight, and long-lasting sensors.

As the world’s first practical FHE device, it offers solutions to challenges in logistics and infrastructure management.

Applications

Improving logistics and warehouse management as well as infrastructure management necessitates devices that can be attached anywhere, allow data confirmation remotely without on-site visits, and enable consideration of reduced maintenance.

Optimizing materials and processes is key to making devices smaller, thinner, and lighter. FHE (Flexible Hybrid Electronics) technology enables the creation of thin and lightweight devices, allowing them to be installed even in confined spaces.

To enhance ease of use, we’ve implemented wireless communication. By utilizing BLE (Bluetooth Low Energy) for data transmission and reception, data can be acquired remotely.

To achieve long operating times, we’ve optimized the software. By efficiently operating the microcontroller embedded within the device, it can function for extended periods without needing a battery replacement.

We realize thin and lightweight FHE devices using printed electronics technology.

FHE devices, utilizing printed electronics technology, are incredibly environmentally friendly as their manufacturing process eliminates the need for exposure and etching steps. By integrating existing electronic components onto circuits printed on flexible substrates, we’ve successfully created thin and lightweight FHE devices.

Furthermore, to ensure efficient operation and low power consumption for FHE devices, we’ve optimized the firmware of the onboard microcontroller. Our practical experiments have demonstrated that these devices can continuously measure temperature and humidity data for approximately six months without requiring a recharge. Additionally, the data recorded for a set period isn’t just a single measurement; it logs the maximum and minimum values for that interval. This allows for the detection of sudden temperature changes or anomalies that occur within the monitoring period.

BLE wireless communication enables remote data verification from the field.

By utilizing thin and lightweight FHE devices, we can attach them to confined spaces or objects that were previously difficult to monitor, thereby improving productivity. Data acquisition is possible via BLE wireless communication, allowing you to check data remotely from where the FHE device is installed.

Furthermore, using a gateway enables data to be stored in the cloud, so you can review it from the office without needing to go near the field. Our FHE devices are also equipped with a display, which can show warning indicators when data deviates from set thresholds, allowing you to spot anomalies at a glance without needing to receive the data directly.
