Stretchable on-skin antennas and wireless SAW sensors: design, microfabrication and measurements


Context

In our modern society, the need for continuous knowledge of the human body’s parameters is a growing trend. In this context, a new field has emerged: “epidermal electronics” i.e. a new class of electronics, with devices that are tattooed on the skin in a seamless way and that can stretch, bent, twist or conform to any shape (See. Fig 1)

 

Objectives

The PhD lies at the interface of the fields of epidermal electronics and surface acoustic devices. The goal of the research is to lay the groundwork to a new generation of wireless on-skin stretchable surface acoustic wave sensors enabled by the combination of 3 aspects:
a) Efficient on-skin antennas : this will be one of the major aspects of the PhD thesis
b) Confined WLAW (Waveguiding Acoustic Wave) structures in order to make packageless/self-protected structures[2]. Structures are a combination of thin film materials with specific acoustic and piezoelectric properties.
c) advanced stretchable electronics micro-fabrication using the transfer printing technique

The final goal is to design, make “ready-to-tattoo” wireless sensors operating at ISM frequencies and compatible with industrial specifications.

How to apply

In order to prepare a PhD thesis within the Lorraine Université d’Excellence Program, the interested candidate should consult the PhD topics offered in each social and economic challenges.
These PhD thesis topics are proposed by faculty members or researchers accredited to supervise research.

Candidate application period: according to graduate school schedule

  • visit graduate school web site for application rules. EMMA, doctoral school
  • contact mail adresses :
    doctoral school director
    Denis.maillet (@) univ-lorraine.fr
    secretary chrsitne.sartory (@) univ-lorraine.fr

Each candidate may submit an application on up to three separate research topics.

 

Application analysis period by each graduate school
The graduate school reviews the applicants for a doctoral contract in the relevant disciplines. They check the level of supervision for each supervisor and the situation of trained doctors. Each candidate will meet the laboratory director, supervisor and a representative from the graduate school. This interview is to identify the candidate’s motivations and suitability as a candidate for the PhD project proposed by the supervisor. A recommendation will be made to the graduate school. This will summarize the strengths and/or weaknesses of the application.

PhD grants will include monthly income for the PhD student (roughly 1700 € for research only, complement can be provided for teaching missions) and environment for research in the research unit.

Please be aware that in order to offer a variety of subjects, more positions are posted here than available funding. The LUE executive committee will make the final choice on the granted funding (up to 12 positions), based on the recommendations by the doctoral schools.
