Experimental and Numerical Investigation of a Photoacoustic Resonator for Solid Samples: Towards a Non-Invasive Glucose Sensor
Sensors, 19(13)
29 Juni 2019

Marker: TI-MP

Zusammenfassung: T-cell resonators have been used lately for non-invasive blood glucose measurements for photoacoustic spectroscopy on skin samples. A resonator has a significant role in determining the strength of the measured signal and the overall sensitivity of the sensor. Here we present results of the measurement of the photoacoustic signal of such a T-cell resonator. The signal is also modelled using the amplitude mode expansion method, which is based on eigenmode expansion and the introduction of losses in the form of loss factors. The measurement reproduced almost all the calculated resonances from the numerical models with fairly good agreement. The cause of the differences between the measured and the simulated resonances are explained. In addition, the amplitude mode expansion simulation model is established as a faster and computationally less demanding photoacoustic simulation alternative to the viscothermal model. The resonance frequencies from the two models differ by less than 1.8%. It is noted that the relative height of the amplitudes from the two models depends on the location of the antinodes within the different parts of the resonator. The amplitude mode expansion model provides a quick simulation tool for the optimization and design of macro resonators.

Lifestyle interventions in Muslim patients with metabolic syndrome-a feasibility study
European Journal of Clinical Nutrition, 75(5):805-808

Marker: LS-GW

Zusammenfassung: Obesity, metabolic syndrome, and type-2 diabetes mellitus are common in Muslim patients living in Germany, most of whom are of Turkish origin. Lifestyle interventions must be tailored to religion and ethnicity. We tested the body weight-reducing effect of a 30% calorie-reduced intake diet, adjusted to individual energy expenditure, eating habits, and food preferences in a Turkish-background cohort. Eighty subjects were randomized to activity advice only or to a step-count device to monitor and document physical activity before and after the 12-week intervention. Fifty-three patients completed the study. Lifestyle interventions were effective in these Muslim subjects. Body weight was reduced by 6%; activity monitoring provided a modestly increased effect to 8%. Blood glucose, HbA1c, triglycerides and cholesterol improved also substantially. Subjects receiving metformin could reduce their dosage. Our data show that Muslim Turkish patients respond to interventions if these are tailored to their needs.

An Energy-aware IoT Node for Sustainable Urban Sensing
Proc. of International Conference on Networked Systems (NetSys 2019), Demo Session
Verlag: IEEE Press, Piscataway, NJ, USA

Marker: TI-I

Zusammenfassung: This demo presents an energy-aware system designed for long-term deployments in urban sensing. It consists of a hardware-software co-design that allows for measuring and harvesting energy on class-1 IoT nodes. We focus on the self-management of energy and its integration with the RIOT operating system. The measurement module is composed of commodity components and designed for easy, flexible integration with various hardware platforms.
