Blood testing has traditionally been the gold standard for the physiological analysis and monitoring of professional athletes. In recent years, blood testing has moved out of the laboratory thanks to portable handheld devices, such as lactate meters. However, despite its usefulness and widespread use, blood testing has several drawbacks and limitations, such as the need for the athlete to stop exercising for blood extraction and the inability to have data continuously collected.

However, RDTs have limitations such as low sensitivity and qualitative responses that rely on subjective visual interpretation. Additionally, RDTs are made using paper-bound reagents, which leads to batch-to-batch variability, limited storage stability and detection of only the analytes they were designed for.

- - Recent research focused on self-powered devices highlights their potential benefits for the Internet of Things, particularly in reducing costs, minimizing power use, and lessening environmental effects.
- - A study investigates a wireless sensor node that combines a thermoelectric generator to power itself and measure temperature gradients, specifically for improving server load management in data centers.
- - The proposed system effectively utilizes a maximum power point tracking algorithm, achieving accurate temperature gradient measurements with a maximum error of just 0.14 °C and an energy efficiency exceeding 92% when temperatures are above 13 °C.
A novel self-powered point-of-care low-power electronics approach for galvanic cell-based sample concentration measurement is presented. The electronic system harvests and senses at the same time from the single cell. The system implements a solution that is suitable in those scenarios where extreme low power is generated from the fuel cell.

POC devices have the potential to match or surpass conventional systems regarding time, accuracy, and cost, and they are significantly easier to operate by or close to the patient. This strongly depends on the availability of miniaturized measurement equipment able to provide a fast and sensitive response.
