An　electrically　heated　microelectrode　chip　(HMEC)　was　designed　and　the　Ru(bpy)(3)(2+)/carbofuran　electrochemiluminescence　(ECL)　systems　were　applied　to　characterize　the　performance　of　the　HMEC.　The　ECL　intensities　increase　at　elevated　electrode　temperature,　and　the　detection　limit　at　60　degrees　C　(electrode　surface　temperature)　was　about　10　times　lower　than　that　at　30　degrees　C.　The　results　indicate　that　new　heated　electrode　can　be　handled　easily　and　can　be　mass　produced,　the　difference　between　the　electrodes　was　little.　The　stability　of　the　HMEC　was　good　since　the　electrode　surface　can　hardly　be　destroyed　during　detection　and　storage.
