Can we see the signal?
If bladder filling produces a repeatable body-surface signature, candidate sensors and models should detect it above motion, posture, and coupling noise.
Illustrative hypothesis, not measured DryNight output.
A bladder-state sensing concept for bedwetting
Measure bladder state, not wet fabric.
DryNight is exploring whether a lower-abdomen wearable could estimate bladder filling overnight and support a private cue before wetness begins.
Pre-prototype. No DryNight sensor data. Not clinically validated or FDA-cleared.
A private timing system for the night.
The physical system is still a design direction. Stage 0 is the non-human bench feasibility phase that will determine the sensing modality, body interface, electronics, and whether this form factor is worth pursuing.
Candidate bench architecture
A scoping diagram, not an engineering specification
-
Body interface
Placement and coupling
A repeatable bench fixture before any on-body work.
-
Open decision
Candidate sensing module
Ultrasound, bioimpedance, or another noninvasive approach selected by evidence.
-
Acquisition
Front end and processor
Raw signal capture, known test conditions, local processing, and timestamped logs.
-
Connectivity
Low-power wireless link
A proposed link to the cue endpoint with observable delivery and failure states.
Proposed child endpoint
A private haptic cue band. Cue effectiveness is a separate human-factors question after sensing feasibility.
Proposed caregiver endpoint
Optional escalation by family plan. No notification logic is claimed or implemented.
-
Sensing core
Candidate sensing, processing, and power architecture.
-
Skin interface
A proposed coupling layer designed around stable contact and comfort.
-
Private cue band
A proposed child-first haptic cue before optional caregiver escalation.
-
Charging dock
A proposed home base for charging and device handoff.
The proposed night loop, in motion.
The film shows the current product direction: sense first, cue the wearer privately, and involve a caregiver only by plan. It is a design study, not a demonstration of working hardware.

- 01. The sensing core, skin interface, cue band, and dock appear as industrial design concepts.
- 02. An illustrative signal rises toward a proposed pre-void threshold.
- 03. The child receives a private cue before an optional caregiver step.
- 04. The film closes on the Stage 0 bench-feasibility partnership request.
Two hypotheses. Both have to hold.
Can the cue change the night?
If a discreet cue is delivered at a useful time, can it help a sleeping child wake without unacceptable sleep disruption or caregiver burden?
Illustrative sequence. Cue effectiveness has not been tested.
The next milestone
Bench feasibility, not a product launch.
- 01
Signal screening
Compare candidate modalities under controlled fill, placement, motion, and coupling conditions.
Decision gate: Stop if no repeatable bladder-related signal is detectable above noise.
- 02
Body interface
Test contact stability, positioning, materials, power, and thermal constraints on bench fixtures.
Decision gate: Redirect if stable coupling or practical packaging is not credible.
- 03
Go or redirect
Review the bench data and decide whether to build a body-worn prototype, change modality, or stop.
Decision gate: Advance only if the evidence supports the next experiment.
