Product Planning & Development
From concept creation all the way to mass production and market launch—
Harnessing our in-house “manufacturing expertise” to keep creating innovative products.
In-House Development That Refines Our Ability to Deliver
E3 is a specialist in development and manufacturing, handling every stage from concept creation to mass production and market launch. Since our founding, we have brought a wide range of in-house products to market—from environmental sensors and wellness devices to the Thermal Runaway Shield, which suppresses thermal runaway, and even battery management systems for aircraft and satellites. It is our fully integrated setup—covering electronic circuit design, firmware development, cloud integration, and mass production—that underpins our robust ability to make these ideas a reality.
Contract Development as a Co-Creation Partner
We also leverage this technological foundation in co-creation efforts with companies and research institutions. Starting from the idea phase or Proof of Concept (PoC), we offer one-stop support for everything from functional testing, cost optimization, and certification acquisition, to mass production design. Far from being a mere subcontractor, we act as a partner who shares your business goals, working together to create new value.
If you’re looking for a sure way to transform your vision into a product, don’t hesitate to reach out. E3 will bring your ideas to market in the shortest possible time, backed by our extensive experience and technological capabilities.

Past Development Achievements
Thermal Runaway Shield
Suppressing and containing
thermal runaway
Thermal Runaway Shield (TRS) is an advanced shielding technology that suppresses and contains thermal runaway—an issue that can occur in lithium-ion batteries. Employing a proprietary carbon fiber structure also utilized in NASA’s research, TRS effectively controls the spread of heat and flames between battery cells. As a result, it significantly reduces the risk of smoke or fire, delivering high levels of safety and reliability across a wide range of energy storage systems.
Battery Management System
BMS for
aircraft and satellites
Our Battery Management System (BMS) for aircraft and satellites is a high-reliability platform that optimally controls charging and discharging of lithium-ion batteries used in communication systems, while monitoring remaining capacity and degradation in real time. In compliance with aerospace standards, it features redundant designs and high-speed telemetry. By precisely analyzing factors such as temperature, internal resistance, and cell balance, the system ensures battery safety and mission continuity even under harsh conditions.
caboc
(Discontinued)
A one-finger
carbohydrate monitor
“caboc” is a health management device that visualizes how carbohydrates are absorbed into the body and how they change over time. With this single device, you can measure your data anytime, anywhere with just a single finger. Your results can be checked immediately in the dedicated app. Regular measurements will display daily changes in graphs or lists—helpful for those who want to manage their health more effectively.
airmon
(Discontinued)
A palm-sized
PM2.5 measurement device
Used in conjunction with a dedicated app, this device allows you to easily check pollution levels in everyday spots like your home or a local park. It requires no complicated settings: just install the app on your smartphone, link it with airmon, and you’ll instantly know the air quality in your area. In addition to PM2.5, it can also measure pollen and tobacco smoke (shown as “PM10”). The application is free and can be used by anyone.
petoco
(Discontinued)
Enhancing family conversations
in a fun way
In Japan, the number of dual-income households is on the rise. Even if they live under the same roof, differences in daily schedules can lead to reduced conversations with one’s spouse or children. This issue inspired the development of petoco, a home communication device that aims to solve this problem in a fun way.

SleepingMonitor
(Discontinued)
An
ultra-compact sleep monitor
“SleepingMonitor” is a health management device that easily tracks your sleep. By recording your sleep patterns, you can manage your daily health more effectively. It can even measure nighttime body temperature, which is notoriously difficult to track, helping you maintain a better overview of your daily well-being.
E3PHONE
(Discontinued)
A new form of
landline phone
An “audio telephony hub” with no dial or handset. You can register up to five smartphones as cordless units, and even when you’re out, you can still receive incoming calls and talk through your smartphone!
BonLotus
(Discontinued)
A safe and gentle antibacterial &
deodorizing spray
This weakly acidic hypochlorous acid water for disinfection and deodorization can be used with confidence in various situations.
