This This paper presents the study of an ESP32-assisted instrument for geolocation and detection of child ECG. The aim is to highlight the ingenuity and interest of the proposed instrument. This instrument differs from most similar products in existence by its multiple geolocation features of the child based on a GPS module (Ex: Type NEO-6M-0-001), and telemetry of the child's heart rate by ECG probe (e.g. type AD8232). Analog-to-digital conversion and digital processing of vital GPS and ECG signals on the child’s body is a microcontroller mini-card (e.g. ESP32), which then transmits digitally reconstructed vital parameters via a computer. The algorithm of the proposed instrument, is implemented using the CAD software Arduino/EDI - C++, followed by the download of the executable code on target ESP32 and the real-time test successfully on a child model of 1 year 6 months. Local measurement and monitoring results of geolocation and acquisition of ECG are satisfactory. We plan to extend the local virtual monitoring technology of this new instrument, to cases of mobile Android targets via the Internet.

This article concerns the study of a measuring instrument controlled by ESP 32 with local monitoring of biological parameters providing information on the state of scarring of human skin with 2nd degree burns; A brief review of the literature on existing or deployed therapeutic techniques and means for people suffering from 2nd degree burns is presented and allowed us to study the characteristics that led to the establishment of an architecture of the new proposed biomedical instrument. This electronic instrument consists of: a dimensional sensor (depth and thickness) of the wound; a sensor for humidity and thermal states (hypothermia and hyperthermia); a cardiac parameter acquisition sensor, a microcontroller mini-card which manages the A / D conversion and digital processing of measured biological quantities, with monitoring of these quantities on an LCD display. The virtual simulation results with a functional aspect obtained are validated in the PROTEUS software of said instrument, which are presented and then interpreted, prove to be satisfactory; the experimental workshop and the main results obtained are presented. These give very good results since in addition to the completely stable acquisition of biological parameters, the proposed system does not interfere with devices emitting electromagnetic radiation. Thus, a first prototype of this proposed instrument was produced, with a view to embedding it in a new biomedical therapeutic suit for people with 2nd degree burns.
