Bedwetting alarm pants

Bedwetting alarm pants, are they different from ”traditional” underpants? Do you always need bedwetting alarm pants and how do bedwetting alarm pants contribute to solving the bedwetting problem?

Bedwetting alarm pants are in fact different from traditional underpants because they contain sensors that detect when urine hits the pants and they produce a signal as this happens. Of course ”normal” underpants don’t do that, so our preference is always for sensor underpants when you want to solve bedwetting problems.

Traditional underwear vs. bedwetting alarm pants

We now know that bedwetting alarm pants contain sensors, but how does this work exactly? These special pants are equipped with thin threads made from copper or stainless steel, so thin even that you won’t feel them when wearing the bedwetting alarm pants. These threads react to the resistance that is created when moisture gets on the threads and thus provides a signal. The matching sensor is then triggered and thus provides a signal to wake the child up. Thick can be an alarm bound or a vibrating function of a matching object for example. Different brands have their own way of doing that.

Normal underwear has no extra functionalities and will therefore not be able to send out a signal when your child wets the bed. This can be solved by having a separate transmitter that is attached on the underpants somewhere. When it comes in contact with moisture, the transmitter will react. In our opinion this is a drawback because the transmitter always has to be attached to the cross, as close as possible to the place where the moisture is first noticeable, this is at the expense of wearing comfort.

Bedwetting alarm method

The bottom is an essential part of the bedwetting alarm method. The special threads in the shorts activate the transmitter and send a signal to the receiver. The receiver can be seen as an alarm with a certain sound that wakes up the child. This stops the peeing and the child can go to the bathroom to continue peeing. Without special underwear, the bedwetting alarm method cannot function.


So the pants have special threads that are at the base of the operation of the entire bedwetting alarm. These wires determine whether or not the transmitter should send a signal to the receiver. When moisture gets on one of the threads a signal is sent directly to the transmitter and because the transmitter is in contact with the receiver it will give an alarming sound.

Because the transmitter is supposed to be in contact with the shorts, in many cases it is attached to the shorts with snap buttons. It is important here to look at what is most comfortable for the child. We get feedback that a transmitter that is positioned at the height of the strap of the shorts is the best. At this location, the child has virtually no trouble with the transmitter when he or she is in bed.

Washing instructions

Electronics and moisture don’t usually go well together, but what about bedwetting alarm pants? Of course you are not supposed to put all accessories in the washing machine. Only the pants can be washed in the washing machine because the stainless-steel threads can withstand the moisture. We therefore recommend that you do not wash the bottoms pants higher than 60°C.

Tip: we always recommend purchasing a mattress protector because an accident can occur on a everyday basis. A mattress protector ensures that the pee does not get directly into the mattress. In our blog why a mattress protector we explain this in more detail.
