Abstract: A smart diaper system and methods for making the same. The system includes a diaper, an embedded sensor array, fixed to the diaper, including at least one sensor configured to detect a stimuli and a wireless transmission module operably connected to the embedded sensor array, configured to transmit a signal to a peripheral device. Additionally, in response to detecting a stimuli, the embedded sensor array communicates with the wireless transmission module to transmit a signal to the peripheral device corresponding to the detected stimuli. The method for manufacturing a smart diaper system includes providing a diaper, providing an embedded sensor array, including at least one sensor configured to detect a stimuli. Additionally, the embedded sensor array consists of screen printed sensors printed directly on a thermal transfer substrate and the thermal transfer substrate featuring the embedded sensor array becomes a fixed integral part of the diaper.
