After the launch of the USB pregnancy test, it was only a matter of time before the technology was used in more birth-related gizmos.   

 Joining the ranks of numerous DIY home medical tests is DuoFertility, a heat-sensing skin patch that records temperature of the woman wearing it to establish the baseline of her body’s basal temperature (BBT) which indicates the time of ovulation. Created by a company founded by Cambridge University PhD students, the patch records over 20,000 more temperature readings than other fertility temperatures and records them through the included reader or via a USB download on any compute helping couples plan conception. Costing around $1,000, DuoFertility is expected to hit European markets later this year.
