DryNight

In development · for children who wet the bed

Measure bladder state, not wet fabric.

DryNight is a soft patch, worn low on the belly, being designed to sense bladder filling before wetness starts, cue your child privately, and bring you in only when it helps.

“My son wets the bed every night, the way I did as a boy. I am building what I wish we had.”
Ndansi Elvis Nukam, Founder & CEO
DryNight app estimating bladder filling on a sensing arc

Stage

In development

Concept and feasibility planning. No finished device yet.

Who it is for

Children who wet the bed

Pediatric nocturnal enuresis first. No adult use until the pediatric work is done.

The hard problem

Overnight signal quality

Motion, posture, contact, power, comfort, false alerts, and useful lead time.

Next step

Feasibility testing

Test whether bladder filling can be estimated early enough to cue before voiding.

Concept-stage only. Not clinically validated, FDA-cleared, or available for diagnosis, treatment, or medical decision-making.

The founder

I wet the bed until I was twelve.

I grew up in Cameroon. My grandparents tried everything: raw okra, anthills, every remedy the village knew. Nothing worked. I stopped going to boarding school so no one would find out. I became the cleanest, most driven student I could be, because I was convinced no one could ever know what I was hiding at night.

Now my nine-year-old son wets the bed every night. His is more severe than mine. I refuse to shame him the way I was shamed. But the best alarms on the market still have cords, still detect moisture after the fact, still fail him.

So I started building what I wish I had. DryNight begins with my son, but the standard is broader: a child should not have to be wet before the system understands that help is needed.

The public record ↓

01 · Problem

Most products react after the bed is already wet.

Moisture alarms can help some families, but they usually detect urine after it reaches clothing or bedding. DryNight starts from a different question: can a comfortable overnight patch estimate bladder filling early enough to cue before voiding?

  • Current alarms detect wetness

    Moisture clips are useful for some families, but they begin after urine reaches clothing or bedding.

  • Clinical care still needs better home tools

    Behavioral care, medication, and alarms all have roles. The missing product category is an earlier bladder-state signal that families can use at night.

  • Families need earlier information

    The intended product is a quieter signal before the event, with caregiver escalation only when it helps.

bedtime morning CUE THRESHOLD DryNight cues here alarms react here the lead time we are trying to win

Illustrative concept, not measured device output. The product question is whether that cue window can be detected reliably and comfortably overnight.

02 · Current solutions

Families already have options. None of them act before the bed is wet.

Bedwetting alarms, medication, behavioral programs, and existing bladder sensors each do real work. None of them gives a private cue at night, before voiding. That gap is the product DryNight is being built for.

How current bedwetting approaches compare with DryNight’s proposed pre-void cue.
Moisture alarms After wetness reaches clothing or bedding Weeks to months of consistent nightly use; tolerating a 2am alarm and laundry Reacts to the event it is meant to prevent; many families stop before it works
Desmopressin Reduces overnight urine production A prescription, fluid limits, and management of relapse on stopping Manages symptoms pharmacologically; relapse is common and it does not teach timing
Behavioral and urotherapy Over weeks, through daytime habits and bladder training Sustained effort from child and caregiver; clinic follow-up Slow, effort-heavy, and not a nighttime signal
Daytime bladder sensors (SENS-U) Notify when the bladder is near full, primarily for daytime urotherapy Wearing and charging a lower-abdomen ultrasound sensor Built around daytime full-bladder notification and urotherapy; the nocturnal pre-void cue remains unproven
DryNight (proposed) During sleep, before voiding, at a chosen fill threshold A comfortable patch and a private wrist cue; caregiver escalation only by plan Unproven. This is the hypothesis DryNight has to earn through feasibility work.

DryNight is concept-stage. The comparison describes intended product direction, not validated performance. The SENS-U row reflects a real commercial device; see the evidence room for citations.

03 · Night loop

You see the plan. Your child gets the first quiet cue.

The product is being designed around dignity first: the wearer, whether a child, an adult, or an older adult, gets a private signal before a caregiver is brought in.

DryNight app: Sense overnight
02 · Sense overnight

DryNight app: Cue privately
03 · Cue privately

A private wrist cue first. Caregiver only if needed.

The loop, four moments.

  1. 01 Before bed

    Place the patch once

    The lower-abdomen patch has to be soft, cordless, and stable enough that setup does not become a nightly argument.

  2. 02 During sleep

    Estimate bladder filling locally

    Raw sensing should stay close to the device while the system looks for a conservative threshold, not a diagnostic conclusion.

  3. 03 First cue

    Cue the wearer privately

    The cue should be private and gentle before a public alarm or caregiver escalation is considered.

  4. 04 Escalation

    Bring in help only when needed

    Caregiver alerts should be configurable, minimal, and reserved for moments when the private cue alone is not enough.

The hardware path can change. These product standards should not.

  • Private by default

    No loud bedroom alarm as the default interaction.

  • No claims before evidence

    No performance numbers until a study supports them.

  • Comfort before dashboards

    A family will not use a better signal if the device is hard to wear.

For families

The questions a parent actually asks.

Straight answers, including the ones that are still "we do not know yet."

We will never share your address. This is not a medical service.

Is sensing my child’s belly every night safe? +

The lead approach is low-power ultrasound on the lower abdomen, related to sensors already used in children, but DryNight’s intended use is different: continuous, every-night, all-night sensing. That continuous use pattern is exactly what safety and human-factors work has to establish on its own; we do not assume it is safe because a daytime sensor exists. We will not ask a family to use it until that work is done and reviewed.

What would my child actually wear? +

The intended design is a soft patch on the lower abdomen and a wrist cue, not a cord clipped to pajamas. Comfort is treated as a primary product gate, because a better signal is useless if a child will not sleep in it.

Will it wake my child if they sleep through everything? +

Deep-sleep arousal is the hardest part of bedwetting and the reason many alarms fail. DryNight starts with a private, escalating wrist cue and lets caregivers decide when an adult is brought in. Whether the cue reliably rouses a child is one of the first things the feasibility studies have to answer.

When could we try it, and what might it cost? +

There is no product to buy yet and no date we would promise before the science supports it. The most useful thing right now is to leave your email so we can reach out when there is something real to try, and to tell us what the alarm years were actually like.

What can we do tonight, while you build? +

Talk to your pediatrician. Most childhood bedwetting resolves with time, and current options (alarms, desmopressin, and behavioral programs) help many families. DryNight is not a reason to delay care that could help your child now.

04 · Evidence room

Why we think this can work, and what still has to be proven.

Why the idea is plausible, where the first risk sits, and what has to be proven before any family is asked to trust it.

83%

of natural overnight bladder-filling cycles (15 of 18) were detected at home by the SENS-U in 14 children with enuresis, the setting closest to DryNight’s.

[1] Kwinten et al., 2020 ↗

90%

of a controlled clinic urodynamic study (30 children, ages 6–12) had a full, catheter-filled bladder recognized before voiding by the SENS-U. A controlled-fill benchmark, not an overnight result.

[2] van Leuteren et al., 2018 ↗

External findings, not DryNight performance data. They measure detection under different conditions, and in both studies the device only monitored: its alerts were switched off. Neither tested waking a child, so the hardest part of DryNight’s thesis (a cue that rouses a deep sleeper) has no precedent and must be earned.

Problem reality

Before any technical proof, the problem itself has to justify a better product: timing, dignity, and caregiver burden.

  • Bedwetting is common in school-age children and often resolves gradually rather than immediately. [3]

  • Most household alarms start only when wetting begins, long after the bladder first becomes actionable. [3][4]

  • Families need earlier information and less public interruption; a louder signal after wetness reaches clothing or bedding delivers neither. [4]

Technical precedent

Both studies below used a wearable ultrasound bladder sensor (the SENS-U), sold for daytime use in children. That a commercial device already estimates bladder state in this age group makes the sensing approach realistic. DryNight is building the overnight system that category has never attempted: the private cue, the escalation plan, and the home experience.

  • The SENS-U wearable ultrasound sensor detected full bladders before voiding in 90% of a 30-child urodynamic cohort aged 6 to 12. [2][6]

  • In a single-night home session, the SENS-U detected 83% of natural nocturnal bladder-filling cycles (15 of 18) in children with monosymptomatic nocturnal enuresis, without disturbing sleep. [1]

  • Noninvasive bladder monitoring is an active research area across ultrasound, bioimpedance, optical sensing, and flexible ultrasonic devices. [6][7]

Product thesis

The winning product here is a private timing system that fits the home. The sensor is only one part of it.

  • The first product is a soft lower-abdomen patch, a private wearer cue, and optional caregiver escalation.

  • The first milestone is timely pre-void cueing, before wetness starts.

  • The same timing problem can later support adult, older-adult, and caregiver workflows once the pediatric proof point is earned.

Validation milestones

This is the work between a strong idea and a product families can trust.

  • Select the sensing architecture that survives body-size variation, sleep position, motion, adhesion, and power constraints. [6][7]

  • Define an actionable threshold that balances missed cues, false cues, wearer comfort, and caregiver burden.

  • Run repeated-night usability and a clinician-reviewed pilot before expanding the market story. [3][4]

05 · Market focus

Why pediatric bedwetting comes first.

DryNight starts with pediatric nocturnal enuresis because the pain is specific, recurring, and poorly served by existing consumer tools. Adult incontinence may follow, but the first proof has to be specific.

Starting point

Pediatric nocturnal enuresis.

The first user is a child who can sleep through a full bladder and a parent trying to help without shame. The initial product experience should be private, comfortable, and small enough to test rigorously.

Why here first
Families already buy alarms, mattress protection, and repeated workarounds
Validation path
Bench testing, overnight usability, and pediatric continence input

Where this could help next

Long-term care and aging.

The same type of early bladder signal could eventually support older adults and caregivers. That market has different workflows, liability, staffing constraints, and reimbursement questions, so it belongs after pediatric feasibility.

Why later
Home care and long-term care once the signal is validated
Validation path
Workflow interviews before committing to a care-facility study
