Wearable devices with multiple sensors in a single package to consume 31 per cent lesser power with the new application processor TZ1001MBG from Toshiba.

Referring to the release, “The goal for battery-operated wearable devices is a long run time without charging, with a physically small battery. This requires power-saving technologies. MCU embedded in wearable devices typically support several low-power modes. However, the transition from low-power mode to active mode requires some power consumption. This requires wearable devices to reduce the frequency of mode transition. However, the number of sensors embedded in wearable devices is increasing, requiring the microcontroller to respond to sensors more frequently, with a mode transition every time it does. Thus, the technology reduces the frequency of the mode transition by gathering the separate data acquisitions from multiple sensors which get data at their own regular intervals. In this way, the number of mode transitions can be decreased; hence the reduction of power consumption from mode transitions is achieved.”
