The Fall Detection solution identifies fall events from other daily activities such as walking, running, sitting, and climbing stairs. The system is comprised of Renesas RE Family’s ultra-low current consumption MCU and 3-axis accelerometer; the MCU receives real-time accelerometer data during the fall and runs the algorithm to identify the fall.

  • Fall detection can be configured for Object fall or Human fall
  • RE MCU will operate in 3 different power modes to minimize the current consumption
  • RE MCU stays in minimum power standby mode with 0.5µA current consumption for most of the time, when there is no activity (Human/Object movements)
  • After wakeup from standby mode, the fall detection algorithm runs to read and analyze the accelerometer sensor data to detect the free fall
  • Algorithm will capture 600 samples of accelerometer values in iteration.
  • To increase the accuracy, fall detection algorithm uses both LFT and UFT comparison.
  • Trackers
  • Wearable
  • Healthcare
