“…For instance, in the case of batteryless approaches presented in [ 5 , 6 ], the energy is provided by a WPT system to a local energy accumulator and then the measurement is executed. There also exists another common batteryless approach which does not include an energy accumulator [ 7 ].…”

In this paper, a novel application of the Nondominated Sorting Genetic Algorithm II (NSGA II) is presented for obtaining the charging current–time tradeoff curve in battery based underwater wireless sensor nodes. The selection of the optimal charging current and times is a common optimization problem. A high charging current ensures a fast charging time. However, it increases the maximum power consumption and also the cost and complexity of the power supply sources. This research studies the tradeoff curve between charging currents and times in detail. The design exploration methodology is based on a two nested loop search strategy. The external loop determines the optimal design solutions which fulfill the designers’ requirements using parameters like the sensor node measurement period, power consumption, and battery voltages. The inner loop executes a local search within working ranges using an evolutionary multi-objective strategy. The experiments proposed are used to obtain the charging current–time tradeoff curve and to exhibit the accuracy of the optimal design solutions. The exploration methodology presented is compared with a bisection search strategy. From the results, it can be concluded that our approach is at least four times better in terms of computational effort than a bisection search strategy. In terms of power consumption, the presented methodology reduced the required power at least 3.3 dB in worst case scenarios tested.

Aromatherapy is an alternative treatment method that uses essential oil vapors from various plants inhaled for health therapy. It affects mood, reduces fatigue and anxiety, and stimulates relaxation. Relaxation is the process of relieving anxiety or stress. It is interpreted as a calm state with a normal pulse. When someone is stressful and anxious, the pulse is higher. Measuring the level of anxiety is done by measuring the heart rate. The research aimed to design an electric aromatherapy device equipped with Atmega 8-based heart rate monitoring as a therapeutic tool that can help reduce various kinds of health problems, one of which is anxiety or stress disorder. The test was carried out by comparing the values of the heart rate monitoring to a pulse oximeter. The oximeter was used as a reference to get high accuracy values. The device is expected to help reduce various kinds of health problems caused by heart problems.
