We have 3d printed a small and big wristband. The smaller version is for the child to wear and the bigger one is for a parent or guardian to wear.
It was decided that the 3d models’ bands were too hard to manipulate to fit a person’s wrist. We sawed off the faces of the wrist bands and rubber bands were added to stretch and fit the children’s and parent’s/guardian’s wrists. In addition, it would be more comfortable to wear more so than the material used to 3d print the bands. The use of rubber bands as wristband will also be cost-effective compared to other materials being considered (i.e. wood, silicon, etc.)

Through contemplation and discussion, there were three solutions that were being considered to improve people’s ability to save children from drowning.
- Solution #1: Humidity Sensor Alarm
A bracelet would be attached to a child by the parent or guardian when the child is expected to leave the vicinity of the house. The bracelet would have a circuit that will detect water inside of it. Once enough water fills in and completes the circuit, an alarm on the side of the bracelet would sound off which will allow nearby bystanders to save them.
- Solution #2: Bluetooth Bracelet
The idea for this solution is to have a bracelet be connected to another bracelet with an alarm on it. Children would wear the bracelet without the alarm and the parents would wear the bracelets with the alarm. Activation for both of the bracelets is required in order for this solution to be implemented properly. If the child walks out of the range of the parent, an alarm would signal the parents and surrounding people to find the child. This will help improve the parents’ or guardian’s ability to keep an eye on their children.
- Solution #3: Motion Sensor
An adjustable sensor that can be placed near entrances of the house that can alert guardians with a speaker alarm that something has passed. The sensor will emit a laser so when a child passes an alarm would sound off allowing the parents to act. The alarm that is attached near the entrance will have a safety where the parent and/or guardian will able to turn off the alarm if found unnecessary.
Through the method of a Decision Matrix, a solution was chosen.

We have come up with three solutions:
- A bracelet – When submerged in certain amount of water, a life preserver will come out of the bracelet and save the child.
- Wristband with a proximity sensor, such as bluetooth – When a child is at a certain range of distance and when the device is on, the bracelet will beep and alert the parent/guardian who will also be wearing the bracelet.
- An invisible fence – The fence will surround the house. If a child runs too far way or out of range, the fence will send an alarm or beep to alert the parent/guardian
