It can be easily calculated that for a building with 1000 wireless sensors installed, which can be very common for a smart building, assuming a battery life of 3 years, on average, batteries need to b

mm-Wave Monolithic Integrated Sensor Nodes,ed antenna, an RF switch, an on-chip wireless power receiver, and a temperature-correlated ultra-low-power transmitter. It measures only 1.83 mm. in 65 nm CMOS and weighs 1.6 mg. With the on-chip 30/65 GHz dual-frequency antenna and a three-stage inductor-peaked rectifier, the node can be wirelessly
