Micro/nano-spring enhanced photoacoustics: devices, methods and applications

2017-2019

17-05167S, Grant Agency of the Czech Republic (associated contractor - project leader is affiliated with another institution)

An acoustic-wave sensor, as a key element of mechatronic sensing system, makes it possible to investigate thermomechanical phenomena occurring in laser-illuminated matter: looking at heat generation and conduction processes in material, thermal/non-thermal expansion, phase transitions and electrostriction. The photoacoustic detection conducted in non-resonant and resonant regimes sheds light on ablation/desorption-induced stress/strain responses. Micro/ nano-mechanical levers based on micro/nano-springs and micro/nano-scrolls will be utilized for composed photoacoustic and interfacial strain (electro)mechanical sensing. Non-linear dynamics of these elements will help us to investigate their mechanical resonance properties.
