Low frequency noise (500 Hertz and lower), which could stem from various sources such as construction machineries and aircrafts, is a form of environmental noise problem in urban environments. Such noise transmits over long distances and cause disturbance to wide area. It is also known to trigger a number of negative physiological reactions such as…
NUS Innovation Opens Doors to Smaller, Cheaper and Long-Lasting IoT Sensors
Researchers from the Green IC research group at the National University of Singapore (NUS) have invented a low-cost ‘battery-less’ wake-up timer – in the form of an on-chip circuit – that significantly reduces power consumption of silicon chips for Internet of Things (IoT) sensor nodes. The novel wake-up timer by the NUS team demonstrates for…
