The world felt through a robot’s skin

Camilo Rojas (CSEM and EPFL) on WiseSkin:

"WiseSkin envisions an artificial skin with an embedded network of wireless sensors, each of them miniaturised to a size smaller than 5x5x3mm, to provide tactile information to robots and humans wearing prosthetic limbs.

"The network of 6 wireless sensors shown above aims at replicating the communication system in the human body in charge with conveying the tactile signals from the skin to the brain, in order to assess potential improvements in terms of reliability and performance."

Bone Drilling - A Hot Topic

Arne Feldmann (University of Bern) on HearRestore:

"We aim to develop a surgical robot system dedicated for image-guided microsurgery, enabling minimally invasive and atraumatic cochlear implantation. Minimally invasive cochlear implantation involves the drilling of a tunnel from the surface of the mastoid bone, behind the ear, to the cochlea. The accurate placement of this tunnel is of vital importance as it must pass through a region densely populated with vital anatomy, including the facial nerve, which the trajectory generally passes within 0.5 mm. In such close vicinity, heat and vibrations generated by drilling are of potential danger to this and other critical structures.

"To ensure safe and atraumatic drilling of the trajectory, the process of bone removal should be fully understood. Through the optimization of tool-tissue interaction parameters, the creation of drill a hole that is precise and 'cool' is possible. We do so by looking at the micro scale of bone cutting as well as investigating the effects of drill induced heat creation and distribution." arne.png

Miguel Modestino of EPFL:

"SHINE is developing integrated engineering solutions for the fabrication of practical solar-hydrogen generators. Device components (pictured above) include solar concentrators, photovoltaic cells and electrolyzers based on membrane electrode assemblies. The geometry, composition, and operating conditions of each of the components is optimized for operation in integrated solar-fuel generators."

Envirobot is making waves !

Envirobot takes to the water:

Frédéric Truffer of HES-SO Valais :

"The picture shows a remote-controlled boat with an integrated turbidity sensor and built-in communication electronics for real-time data transfer to a computer, placed at the shore. This developed sensor allows first water-quality tests and helps in improving more sophisticated sensors, which will be implemented in the Envirobot."
