PhotoIt's a fact of modern life: anything with a wireless connection has the potential to be hacked, so once wireless baby monitors went on the market, it was only a matter of time before hackers hijacked those monitor feeds so they could spy on strangers' babies.

But if wireless baby monitors aren't high-tech enough for your taste, check out this Wall Street Journal article about the possible shape of things to come: wearable baby monitors that measure everything from your baby's heart rate to sleeping position and send it wirelessly to your smartphone.

Aleks Swerdlow, who is expecting her first baby in July, owns several wearable devices, including a fetal heartbeat monitor. She wants her newborn to eventually wear devices, too.

"I love gadgets, wearables specifically," said Ms. Swerdlow, 29 years old. "So it seemed a natural extension to have that available for my child, especially if it allows me to not worry about how the baby is sleeping and breathing."


Swerdlow, of Santa Clara, Calif., recently paid more than $200 for Mimo Baby, a set of three baby bodysuits that includes a device used to measure respiration, skin temperature and body position. The product sends the vital-sign information to a smartphone. Ms. Swerdlow also is on the wait list for a $250 so-called smart sock made by startup Owlet Baby Care Inc. that senses a baby's oxygen saturation and heart rate.

Though the Journal does discuss possible downsides or concerns related to this wearable new monitoring technology, it doesn't mention anti-privacy or hacker-danger concerns, focusing instead on the possible dangers of babies wearing battery packs or any electronics devices: is there any danger of batteries overheating? Are those electronics made with toxic metals?

Though companies like Owlet say they eventually hope to have their items receive official medical-device status, for now they are careful to state that these are not meant as medical devices of any sort.
