Lithium Polymer Battery LP503035 3.7V 450mAh for wrist-worn swimming wearable
With the successful test of a prototype (built-in Lithium Polymer Battery LP503035 3.7V 450mAh) for children’s’ safety swimming, the waterproof wrist-worn wearables turn into the viable product in the market. It’s great fun for many children to learn to swim, but security has always been a problem. To deal with the safety issue, a wrist-worn wearable for swimming is born, which enable parents and lifeguards to monitor the kids more easily by visual and tactile.
As we known, the swimming places, whether beach or swimming pool, it’s quite noisy. So it becomes the most difficult part that transmits communication between children and families.Let’s see how does this new product become a reality. It began with the prototype, made of PCB, LED light and lithium polymer battery, and it was housed in a box heading to a river for the test. It tests the safe range which allows family members to transmit the signal in the distance, but also test when the safety band would be submerged.
There comes the wrist-worn swimming wearable. Different from other swimming wearables, there are two essential advantages.
First, it is wrist-worn. Comparing with wearing around the neck, it’s more comfortable to wear around wrist. And with an attractive appearance, looks like a bracelet.
Second, you can download the app with a simple interface display, parents could check-in by a glance, and receive alerts from the children if they were out of safe range or in distress.
The successful test of the prototype is the turning point of new wrist-worn swimming wearable, which also owes to lithium polymer battery with an extended service life.
