eDermis
®
Using quantum tunnelling sensing principles, eDermis enables piezoresistive touch, force, and position measurements in a compliant and flexible package. The e-skin uses only 4 wires (about as thin as 2 human hairs), and is highly customisable in size, shape, and number of tactile sensing regions.
eDermis Dev Kits now available

Dev Kits are the perfect way for prospective customers to get a feel for how great our tech really is.
Our latest production run, DK1, will be available shortly. customers can get their hands on our newly optimised sensors, readout electronics, and firmware!
eDermis Core Features:
®
Customise & Embed
A variety of substrate materials, force ranges, shapes, and form factors are available, ensuring perfect integration into your project.
Pressure, Location and Magnitude with TrueResistance™
X and Y outputs for location. Z output corresponds to the resistance due to the pressure applied. TrueResistance™ data allows you to do more, but a simpler voltage-equivalent readout is also optional. Multiple resolution options available with our custom DAQ.
Flexible and Conformable
eDermis can be wrinkled, bent, and wrapped around nearly any hard or soft surface.
Dynamic Force and Pressure Range
Nominal ranges for the eDermis sensors are 0.01 - 30N (Force) and 500Pa - 160kPa (Pressure). Both of these ranges are tuneable, to suit whatever needs you may have.
Thin yet
Robust
As thin as 2 human hairs at 0.2 mm, with extremely high robustness. Durable to more than 1 million cycles of compression or flexing with a reliable output.
Intelligent
Technology
Sensor achieves high data density with only 4 wires, ensuring that DoF of robots are maintained without a rat’s nest of wires. Optimised software and real-time visualiser included. Custom deep learning and sensor data processing applications are also available on request.
Shear & Triaxial e-skin
Our triaxial e-skin is our truly unique, signature, sensor technology. It is the culmination of 7+ years of experience determining the best design, materials and parameters for the ultimate e-skin - which sits in its own class. It goes beyond the capabilities of eDermis® as well as that of human skin, by sensing normal and shear forces for each tactile pixel (tactel) over a massive dynamic range and millions of cycles.
The breakthrough innovation here lies in its form factor, scalability, mass-manufacturability, and ability to integrate into vast compliant arrays over any desired surface. The technology can be used as individual sensors, or a 'skin', where multiple tactels are integrated into an array for high resolution over any surface. The e-skin can withstand harsh and corrosive environments too.
For those wanting to build their own applications, the output of our custom readout electronics is a simple Cartesian XYZ vector that expresses both magnitude and 3D direction of the force applied. The triaxial e-skin can then be used to accurately acquire data from contact surfaces that are soft or hard, flat or round. It can often replace bulky and rigid Force Torque (F/T) sensors which are used to estimate these contact forces.
Added Triaxial Core Features:
3D Force, Magnitude, and Direction
Outputs a 3D Cartesian force vector for each tactel, representing both shear and normal forces. Can be integrated into dense matrix arrays.
Deep Learning and Analytics
Object shape classification through touch, texture detection, slip detection, and ground reaction forces can be accomplished using an optional software add-on.
Piezoresistive and Capacitive
Quantum tunnelling and capacitive capabilities integrated into the same sensor to deliver a massive dynamic range as well as a linear output option. An additional proximity sensing feature can be enabled. Only 5 wires are required for individual sensors.
