This project tackles the problem of miniaturizing biomedical sensors by designing a brand new wireless device used to measure vital signs using electrocardiogram and photoplethysmogram signals as well as body temperature. The starting point of this project is wearIT4Health, a similar project conducted by the research laboratory supervising me, Microsys. Adequate electronic components are discussed and chosen permitting the best miniaturization possible. Moreover, electronic schematics are presented and explained as well as the printed circuit board design of 2 prototypes: one without microcontroller, due to the worldwide shortage in integrated circuit availabilities, and one with. Furthermore, the software running the microcontroller on the board it is soldered is presented and described as well as how data is transmitted from the sensors to the microcontroller. After that, the chosen wireless communication protocol, Bluetooth Low Energy, used to transfer data from the microcontroller to the pairing device is explained as well as how data will be collected and displayed on this pairing device, being an Android smartphone. Finally, tests are conducted on both prototypes and some parts of the device are validated: the battery management system, the radio frequency part and the body temperature sensor. This project is thus a proof that biomedical sensing devices, even very recent such as wearIT4Health, can be further miniaturized to improve comfort of the patient and reduce nurses amount of work.

Smart, wearables devices on a miniature scale are becoming increasingly widely available, typically in the form of smart watches and other connected devices. Consequently, devices to assist in measurements such as electroencephalography (EEG), electrocardiogram (ECG), electromyography (EMG), blood pressure (BP), photoplethysmography (PPG), heart rhythm, respiration rate, apnoea, and motion detection are becoming more available, and play a significant role in healthcare monitoring. The industry is placing great emphasis on making these devices and technologies available on smart devices such as phones and watches. Such measurements are clinically and scientifically useful for real-time monitoring, long-term care, and diagnosis and therapeutic techniques. However, a pertaining issue is that recorded data are usually noisy, contain many artefacts, and are affected by external factors such as movements and physical conditions. In order to obtain accurate and meaningful indicators, the signal has to be processed and conditioned such that the measurements are accurate and free from noise and disturbances. In this context, many researchers have utilized recent technological advances in wearable sensors and signal processing to develop smart and accurate wearable devices for clinical applications. The processing and analysis of physiological signals is a key issue for these smart wearable devices. Consequently, ongoing work in this field of study includes research on filtration, quality checking, signal transformation and decomposition, feature extraction and, most recently, machine learning-based methods.

The aging population and the increased prevalence of neurological diseases have raised the issue of gait and balance disorders as a major public concern worldwide. Indeed, gait and balance disorders are responsible for a high healthcare and economic burden on society, thus, requiring new solutions to prevent harmful consequences.
