Development of a multi-species miniaturized tactile display
ESR3
Objectives
Develop a miniaturized device able to stimulate the skin at multiple length and time scales. This device will be based on an established technique aimed at creating sub-surface stain fields targeted at the cutaneous mechanoreceptors by modifying boundary condition of finger pads or of robotic tactile sensors in the tangential direction. The current system based on piezoelectric actuators has unique capabilities but is expensive, complex to commission and has intrinsic limitation on terms of spatial and temporal resolution. The project will also explore, with ESR1, the development of a 2-stage electromagnet device making it possible to adjust the spatial and temporal resolution to various targets.
Expected Results
A miniaturized device able to stimulate the skin at multiple length and time scales.

My namne is Yerkebulan Massalim. I received the B.Eng. in Electrical Engineering degree in 2017 and M.Sc in Roboitcs degree in 2020 from Nazarbayev University, Nur-Sultan, Kazakhstan. I worked as a hardware engineer from 2017 to 2018 on several embedded systems projects. I’m currently a PhD student at Sorbonne University and works in the R&D department of Actronika, Paris. My research interests are haptics, tactile sensing, embedded systems, and machine learning.
PhD goals
This thesis has a dual purpose.
First, it addresses practical issues, that is, to design haptic displays that can provide intuitive and realistic haptic feedback with simple design. The work rests on designing distributed tactile displays that can provide complex spatiotemporal stimulation using simple yet elegant mechanical design.Tthe display will be used in applications without complex hardware and precise engineering. Second, it has a scientific endeavor investigate texture perception.This scientific part of the research is ranged around identifying invariances and essential cues that constitute the texture perception.
Results
Analyse closed-form electro/thermal scaling laws for miniaturization. Realise computer aided-design based on the analysis and perform multi-physics simulation. Implement physical miniaturized system.
