Watttron’s heating pixels are resistive heating circuits – typically 5 × 5 mm in size – applied to thin, electrically insulated ceramic substrates using a screen-printing process. Each pixel simultaneously functions as a temperature sensor.
The pixels are arranged in modular matrices and controlled via integrated electronics and a graphical user interface. A closed-loop feedback control system enables each pixel to maintain a precision of ±1 K and achieve heating rates of up to 10 K/s with power densities of up to 22 W/cm².
