In some examples, a system may generate an alternating current signal to one of a first sensor electrode or a second sensor electrode. For instance, the first sensor electrode may be associated with a seatbelt and located adjacent to a torso of a vehicle operator of a vehicle. Further, the second sensor electrode may be positioned to be contacted by or otherwise proximate to another body part of the vehicle operator, such as at least one of an arm, hand, leg, or foot of the vehicle operator. The system may receive from the other one of the first sensor electrode or the second sensor electrode, a signal indicative of a capacitance, and may determine a respiration rate of the vehicle operator based at least partially on the signal indicative of the capacitance.
