Microcontroller-based fetal heart motion emulator / Norzulaikha Zakaria
The previous fetal heart motion emulator system was operated and controlled by a computer. The system was inflexible to be transported from one place to another and required a high cost to build due to the expensive cost of a computer. Nowadays, portable and cost effective systems are required. A so...
