a The conceptual diagram of the smart floor monitoring system and its potential applications of position sensing, activity monitoring, and individual recognition in the smart building/home scenarios. b The assembled triboelectric DLES-mat array with a 3 × 4 arrangement, where the inset shows the three device layers fabricated by a low-cost and large-scale screen printing technique. c The digital photographs of the floor mat array and an individual floor mat with a 40% electrode coverage rate, where the scale bars are both 20 cm. d The detailed electrode layout of the floor mats with different electrode coverage rates from 0 to 100% to achieve distinguishable signal patterns after parallel connection. e, f The operation mechanism of the parallel-connected floor mat array when a person walks on/off a floor mat with e smaller electrode coverage rate and f larger electrode coverage rate, where the output signals with relatively smaller and higher magnitude are generated, respectively.
