Research Interests

Vibrations along surfaces are an important information source for animals. Many animals, for example insects and spiders, are highly sensitive to surface vibrations and can efficiently determine what generated the vibration and from where. Understanding how animals use this information source so effectively can help us design useful technologies that use vibrations along surfaces for information. The recent boom in robotic technologies means that robots and drones will soon be gathering information on our behalf. Detecting vibrations on surfaces therefore has many potential applications within robotics: from inspecting the safety of dangerous areas hit by earthquakes, to monitoring elephant behaviour and poaching risk, to checking for faulty machinery using swarms of drones. This expands our technological use of vibrations beyond monitoring stations to detect earth vibrations or using microphones, towards flexible and mobile surface vibration sensing. Through my current research, I aim to understand how spiders, arguably the surface vibration experts of the animal kingdom, detect and use vibrations through their legs. Through studying spiders, I gain understanding that can be applied to other animals that sense these vibrations, as well as robots. I also use nature for inspiration to develop new types of sensors that will allow robots to use vibrations along surfaces for information.
