This is perhaps the thinnest, lightest, and most convenient wireless temperature monitor for infants and children that we’ve seen yet. The TempTraq differs from its competition in one major respect; it is a single-use, disposable device. At $25 a shot, that may seem a bit pricey, but you never have to worry about disinfecting it between uses.

Another important difference is that it works continuously for 24 hours once you activate it. The device contains a thin, flexible battery, so there’s no hassle with keeping it recharged. And the device has at least a full year’s shelf life, so you can have one or two on hand in case you need it. The monitor sticks to the skin of the child, and transmits continuous readings via a wireless Bluetooth connection. The companion app is available for iOS and Android smartphones and tablets, and you can monitor more than one TempTraq at a time, in case you have more than one sick child at home.

The app shows a graph of the child’s temperature over time, so you can see trends. You can also record events such as the time that medication was given, or when the child had something to eat or drink. The app can also issue an alert if the temperature exceeds specified limits. If you choose, you can also share the temperature record with others, such as a parent or physician. This wearable Health Tech device is one that is likely to bring peace of mind to parents and useful information to guide the treatment of sick children.
