London, June 11.A Briton has developed an electronic device that alerts women whether or not they have taken their daily contraceptive pill and can help prevent unwanted pregnancy.
The Remember Device developed by Lai Chiu Tang, a student at London's Brunel University, reminds the user when it is time to take her pill with a choice of four alerts - an alarm, a vibrate mode, a light, or a dual alarm vibrate mode, reported online edition of BBC News.
The longer the pill is left untaken, the quicker the light or vibrate mode will pulse and the louder the alarm will sound.
The pill is more than 99 percent effective against pregnancies. Research suggests 70 percent of women forget to take one a month, and 10 percent forget it at least four times.
The Remember Device carries one pill packet, and indicates the exact pill the user has to take each day. Further, the machine glows red if the user's contraceptive protection level becomes too low, informing her to use an extra contraceptive method.
