  We consider a novel intermittent status updating model where an energy
harvesting node with an intermittent energy source performs status updating to
a receiver through non-preemptive sensing and transmission operations. Each
operation costs a single energy recharge of the node and the node cannot
harvest energy while in operation. The sensing time for each update is
independent with a general distribution. The transmission queue has a single
server receiving packets generated after sensing operation, general service
time distribution and a single data buffer to save the latest arriving update
packet. Once energy is harvested, the node has to decide whether to activate
sensing to generate a new update or transmission to send the existing update
(if any) to the receiver. We prove that average peak age of information (AoI)
at the receiver is minimized by a threshold-based stopping rule that accepts
only young packets to the transmission server. We then use this result to
address average AoI optimization over the considered stopping rules through
novel hybrid waiting and thresholding schemes. Our numerical results show the
improvements in average AoI maintained by hybrid schemes.
