  For several months now, new working methods, even innovative reorganizations, have been imposed on us in order to continue to advance research and to respond to modern societal challenges. Beyond the human challenges we are facing, technology is more than ever used, in the service of distance working, connected services, for a communicating, reconfigurable and autonomous 4.0 factory.
The health crisis is putting extreme pressure on fixed and mobile network infrastructures, which undeniably represent a strategic challenge for tomorrow. Indeed, a certain number of activities requiring massive use of digital technology may need to continue beyond the current situation.
The 5th generation of mobile telephony telecommunications (the "5G"), which comes at the height of a complex global crisis, is attempting to provide solutions in terms of new frequency bands (current resources are saturated) and more efficient energy management (antennas are becoming progressively smarter by limiting radiation in useless areas).
While 5G will eventually enable greater responsiveness for new applications (such as remote surgery), its actual deployment still represents many technological challenges. For example, while 5G is easily "deployable" in urban environments thanks to the fiber optic networks already in place, coverage of less dense areas remains a challenge for radio-frequency systems ("millimeter" and "terahertz" waves). The use of these new frequencies is also an important element in the perspective of the "6G" expected between 2030 and 2035, since a new standard has just been introduced worldwide for 100 Gbit/s wireless communications. This wifi Wifi of the future, which can be called "TiFi", is an issue to which the IEMN is contributing in the flagship project "UHD Telecoms" with demonstrations at the component and system level related to these new standards. Finally, in addition to the technical issues to which many researchers are trying to find appropriate responses, work carried out on the uses and expectations of the population, at the interface between SHS and technology, is also a challenge, because the in-fine acceptability of these solutions, even when driven by the massive use we make of them, has become an essential point.

A trans-dermal patch for treatment of chronic diseases such as diabetes
|
|
The discomfort associated with the use of needles often leads diabetic patients to become discouraged or even neglect their own therapeutic management.
Today, several technological developments are underway to offer alternative solutions to compensate for (multiple) daily insulin injections.

Microsupercapacitors to power the Internet of the Objects |
|
Supercapacitors are a solution of choice for supplying power to connected objects, especially when their electrodes are made of vanadium nitride. However, the origin of the performance of this material remains unknown. Researchers from IEMN and University of Nantes have elucidated the process and discovered a way to use it for micro-supercapacitors (MSC). This work, published in the journal Energy & Environnemental Science, paves the way for extremely efficient and robust MSCs. |

Modulating the elastic properties of a material by light stimuli
|
|
The propagation of an elastic wave in a metamaterial, manufactured by 3D printing, can be modulated by illuminating it in a targeted manner with a laser beam. This result, achieved jointly by the IEMN, the Polytechnic of Turin, Empa Dübendorf and the Norwegian University of Science and Technology in Trondheim, opens the way to the realization of adaptable components for the control of elastic waves.

Ultra-high-vacuum 3D printing for mesoscopic components |
|
Very precise control of semiconductor crystals at the nanometer scale has become essential for the manufacture of advanced electronic components or for certain quantum technologies. In this context, nanowires based on III-V semiconductors with low electronic mass have particularly interesting properties. |

2D materials: beyond graphene…
|
|
Graphene is a material famous for its exceptional electronic properties. However, if these properties are to be exploited in real components, it is essential to reduce electronic interaction with the environment as much as possible.

Essay on Machines in General (1786) Raffaele Pisano – Jennifer Coopersmith – Murray Peake |
|
This book is the first of a set of three on the remarkable work of Lazare Nicolas Marguérite Carnot (1753-1823). ''Essay on Machines in General'' (Essai sur les machines en général [1783] 1786) offers information relevant to the modern history and epistemology of physics, mathematics, and, indeed, to all disciplines of science and engineering emerging in the 19th century. |

Neuro‐inspired Information Processing, Alain Cappy
|
|
Since the brain is known to be an extraordinary machine, can we use it as an inspiration to design intelligent and energy-efficient systems? This is the fundamental and pragmatic question asked by Alain Cappy, which he tries to answer in his book 'Traitement neuro-inspiré de l'information' (Neuro-inspired information processing).

Frequency-adjustable surface acoustic wave device |
|
The proposed solution is to modify the electrical conditions within surface acoustic wave (SAW) devices to vary their operating frequency, i.e. to make SAW filters frequency agile while preserving the integrity of the filtering function. The modification and control of the operating frequencies of the devices is performed by an external electrical control. |

Researcher's portrait - Jean-François Robillard
|
|
It is with fairplay and simplicity that Jean-François lent himself to the exercise of portraiture. A teacher-researcher's career path, highlighting some of the highlights of his history and the trajectory of thermoelectric research at the NEI. "The biggest barriers are often in our heads, they don't really exist. We shouldn't compartmentalize things in his mind, there are so many preconceived ideas, especially about academic research and industry".
