An Australian company on Friday announced the rollout of what it said were the world's first electronic underpants, saying its product was able to send text messages if the wearer became incontinent.

澳大利亚一家公司上周五宣布，该公司研制出世界上首款电子内裤，并介绍这款电子内裤在使用者失禁时能及时发送文字信息。

Newly developed electronic underpants can send alerts via text message to carergivers, in the event of incontinence.

Designed for the elderly and infirm（衰弱的，意志薄弱的） , the SIM system will be used in homes for the aged¹ across New South Wales state to monitor incontinence（失禁，无节制） after successful trials in Victoria, the company Simavita said.

"Incontinence management is a key area in which innovative² technologies can benefit aged care," said chief executive Philippa Lewis.

"We developed SIM system to provide greater comfort and dignity to the elderly while aiming to significantly lower costs for aged care facilities."

Simavita said its underpants（衬裤，内衣裤） have a disposable element similar to a regular incontinence pad and include a detachable（可分开的，可拆开的） transmitter（发射机，传达人） that relays readings from the pad's sensor³ strip over a wireless⁴ network to a central computer.

Alerts are sent via text message or over the institution's paging system.

More than 90 percent of Australians living in elderly care facilities are believed to suffer from incontinence - a problem that currently requires staff to carry out frequent manual checks throughout the day.
