Ultimate cold electron bolometer with strong electrothermal feedback by direct electron cooling of the absorber has been proposed. This concept is proposed to overcome the unavoidable contradiction of supersensitive detectors between supersensitivity and supersaturation due to background power load. The effective electron cooling can be treated as strong electrothermal feedback (ETF) similar to TES (transition edge sensor), an unavoidable dc heating for electrothermal feedback is replaced by deep electron cooling removing all incoming power from the absorber to the next stage and keeping minimum temperature. Noise properties (NEP) are considerably removed by decreasing the electron temperature. All incoming power is removed from supersensitive absorber to the next stage of readout system - SQUID.
