The science behind simple.
We develop ultra-low-power gadgets that are simple and smart. From the E-Paper itself to the circuit board, the enclosure and the firmware, every layer is designed in-house.
From pigment to product.
One small team covering every layer a batteryless E-Paper device needs.
E-Paper
We know E-Paper from the pigment up. Panel selection, driving and colour are tuned together: Spectra 6 full colour on 4-inch and 7-inch panels, image conversion that maps photos onto six pigments, and refresh sequences sized to a tiny power budget.
Electronics & PCB
Circuits and boards, designed in-house. NFC antennas tuned to 13.56 MHz, power stages that run without a battery, and validation of every production lot before it ships.
Hardware & enclosure
Products you can hold, built for mass production: a PC skeleton with a TPU frame, CNC aluminium buttons, 9H glass and MagSafe, engineered around iPhone 16, 17 and 18 Pro.
Firmware & app
The firmware on the board and the iOS app that talks to it are written by the same team, together with our own tools for flashing at production scale.
Patented in Japan.
Japanese Patent No. 7901397 covers our method for refreshing an E-Paper display on power harvested from a contactless field: the display data is received while energy is stored, and the panel is then driven from that stored energy with communication deliberately paused. Data packed by colour count keeps the transfer short enough to fit.
Building something that should run without a battery?
We bring these technologies to partners as ready-to-integrate modules.
