Abstract: A method for characterizing particles producing heat when exposed to light. The method includes the steps of stimulating a particle sample alternatingly with homogenous light waves with at least a first wavelength and a second wavelength, detecting by a detector heat radiated by the particle sample as a result of the stimulation, thereby yielding time-dependent images of a modulated heat distribution pattern, converting the time-dependent image of the modulated heat distribution pattern into the frequency domain and demodulating the image of the modulated heat distribution pattern, and determining a physical property of the particle sample based on the at least one demodulated image of heat distribution.

Abstract: A sweat sensing device is described. The sweat sensing device includes at least one swellable component. The sweat sensing device further includes a defined sweat collection area in fluid communication with the swellable component. The sweat sensing device further includes at least one first sensor for directly or indirectly measuring the dimension of the swellable component such that sweat generation rate and/or sweat volume can be calculated from the measure of dimension of the swellable component and the defined sweat collection area.

Abstract: A sample holder for magnetic nanoparticle samples including a plurality of sample wells for holding a magnetic nanoparticle sample, which are distributed on a top surface of the sample holder. The sample wells are distributed such that a first distance between neighboring samples wells and/or a second distance between each peripheral sample well and a respective edge of the top surface of the sample holder and/or a third distance between a deepest point of the sample wells and a bottom of the sample holder is between 1 and 100 times greater than a thermal diffusion length of the sample holder material. The sample holder is used in a lock-in thermography system.

Abstract: A measurement system (1) for characterizing sample tissue (4; 4a, 4b) in a non-invasive way comprises a stimulation device (3; 3a, 3b; 3a, 3c) for thermal stimulation of the sample tissue (4; 4a, 4b), a temperature sensor (2; 2a, 2b) for capturing at least one temperature profile of the sample tissue (4) and a computing unit (11) connected to the temperature sensor (2; 2a, 2b) for processing data delivered by the temperature sensor (2; 2a, 2b). Thermal radiation radiated by the sample tissue (4; 4a, 4b) from at least a measurement area (5) is detectable as a result of the thermal stimulation by the temperature sensor (2; 2a, 2b) during the thermal stimulation of the sample tissue (4; 4a, 4b). The stimulation device comprises a temperature regulating body (3; 3a, 3b; 3a, 3c) which is in continuous contact with the sample tissue (4; 4a, 4b) in a contact area (6) during an entire measurement period.
