In our research, we have tested sensors and figured out three sensors that can provide precise information about the presence of a child without an adult. Our child detection system uses a weight sensor, PIR sensor, temperature sensor, and Paas (IFTTT). The weight sensor under the child and adult seat will determine the information about child presence without an adult, and PIR sensor will be turned on to confirm the presence of a child, and then the temperature sensor will read the information about the temperature inside the car. IFTTT will send alert notifications about the situation inside the car when a child is left alone inside the car. The aim is to develop a child detection prototype that will determine the presence of a child left alone inside a hot car with precise information.
The mechanical characterization of engineered scaffolds, better known as tissue engineering, has aimed to be of aid in organ transplantation and tissue regeneration. The man made design and fabrication of scaffolds help to grow and secure cells into three-dimensional conditions. In tissue engineering, the hydrogel polymer PEGDA, polyethylene glycol diacrylate, is a biodegradable and biocompatible material regularly utilized. In this research, the photolithography technique is executed to fabricate the scaffold. As a result, PEGDA can be controlled to be strong enough to be implanted in human bodies and help many.
