How does Zembro bracelet work?

  • There are two aspects to the concept behind Zembro bracelet. On one hand, you have the Zembro bracelet itself, by which we mean the bracelet. On the other, you have an application that is installed on a smartphone.

  • The Zembro senior wears the bracelet and the connections (family members or other contacts) use the application on their smartphones. The senior doesn’t need a smartphone, computer or fixed-line telephone to be able to use the bracelet.

  • There's a chip in the bracelet that is in constant connection with the telephone network. This is why the senior never needs a mobile phone if the alarm is sounded; the bracelet acts as a telephone.

  • The bracelet is charged via a USB cable that connects to a computer, or a charging plug that goes in a power outlet.

Is Zembro bracelet waterproof?


Yes. Zembro bracelet is completely waterproof and as such, it’s perfect for wearing in the shower or swimming pool.


Is Zembro bracelet suitable for people suffering from dementia?


  • The Zembro bracelet hardware includes an inbuilt option for sending a warning if the senior ‘wanders off’. You can use this to indicate that the Zembro senior may only wander x metres from home. As soon as this distance is exceeded, the Zembro bracelet sounds an alarm and gives its position.

  • However, this function is currently under development. We use the first few months to learn from the few seniors that use this function. If you are interested in helping us further develop this function, please contact us.

  • We do not consider Zembro bracelet to be suitable for people who suffer from severe dementia and have the tendency to remove clothing, et cetera.
