There　are　increasing　interests　in　flexible　electronic　devices　for　sports,　entertainment,　health　monitoring　and　medical　cares.　In　particular,　flexible　sensors　(wearable　strain　senor　or　robotic　controllable　sensors)　attached　on　clothing　or　human　skins　could　be　used　as　a　motion　detector.　Copper　has　been　considered　as　a　potential　alternative　material　for　other　expensive　noble　metals.　By　laser-induced　direct　reduction　and　transfer　printing,　microsensors　based　on　conducting　copper　circuits　was　fabricated　on　polydimethylsiloxane　or　polyimide　as　cheap　and　sensitive　devices.　A　specific　electrical　resistivity　of　240　mu　Omega　center　dot　cm　of　Cu　circuit　was　successfully　achieved　in　an　electrode　of　about　40　mu　m　in　thickness.　We　demonstrate　a　motion　sensing　based　on　laser-reduced　copper　circuits　with　a　high　sensitivity　and　mechanical　robustness.
