Battery Life is Key
Characterizing battery life is critical for developers of portable battery-powered medical devices. Advances in semiconductor technology have enabled most components in a medical device to be integrated onto a single chip, or a system-on-a-chip (SoC). Further reductions in size are constrained by powering technologies like energy storage and harvesting elements. Long periods of sleep/idle, wakeup/active, and short RF bursts create a challenging demand on the battery.
