The READMI project is mainly dedicated to the remote energy input and the remote control of mechatronics systems of micro or meso-scaled mechatronic systems composed of several actuators. These two functions are often performed in a wired way and the increase of wires and connections is a recurrent problem in strongly miniaturised systems. The research works performed in the READMI project are linked to the microfactory/desktop factory concept in which the spacial and functional flexibilities are required as it is an evolvable production system. With the aim to allow flexible production, partners propose to develop the digital actuation principle at meso and micro scales, in order to avoid wires in the mechatronics system environment because this kind of actuators does not need closed loop control then no sensors. The smart control will enable to control selectively actuators, according to the wavelength of incident radiations, or a combination (duo, trio…) of wavelengths, each actuators being only active for a specific spectral stimulus. Moreover, partners of READMI project propose to integrate additional functions in these meso or microactuators, thus increasing the system smartness (position detection and remote communication of this position), without addition of wires nor energy overconsumption, thanks to low-level detectors integrated to the system and possessing miniaturised wireless communication modules and mechanical energy harvesting devices for their energy supply. As a demonstration, these remote control and remote energy supply will be applied the problematic of meso and micro conveyance in the microfactory context. The long term objective is to provide smart conveyance systems for micro-objects entirely wireless and energetically autonomous. For this objective, partners will use their own existing research results and their complementary expertises (design of digital-actuation-based mechatronic systems, design of thin-layers optical filters, development of micro harvesting and storage energy sources, microfabrication techniques). Experimental demonstrators based on these two technologies will be produced : the first one uses digital electromagnetic actuators controlled by selective spectral optical means and the second one composed of bistable structures actuated by shape memory alloys having a spectrally selective activation. A microfabricated electromagnetic demonstrator will enable to validate, in a first time, the principle of the remote control using photodetectors having independent quadrants, each one being selective for one unique wavelength. Two other demonstrators using bistable meso or micro structures actuated by shape memory alloys will also be developed because this technology is more adapted to both remote energy supply and wireless control in the same time. The first one of these demonstrators will enable, at the microscale, the validation of the coupling of energy supply and control without any wires in the workspace of the actuator, while the second one will enable to validate the principles of position detection and transmission of this position by radiofrequency means, as well as the mechanical or optical energy harvesting using piezoelectric or photoelectric components.
