Description
Recent developments in nanotechnology, bioengineering and synthetic biology enable the design of so-called nanomachines (e.g., nanorobots, genetically engineered cells). Due to the limited computation capability of individual nanomachines, it is required that the devices have the ability to communicate among themeselves to achieve complex goals. A promising approach to communicate at this small dimension is to use chemical signals as carrier of information, referred to as molecular communication (MC). In MC a transmitter nanomachine releases molecules that propagate through an aqueous or gaseous environment. The information can be encoded in the molecule concentration, the molecule type or the release time of the molecules. The receiver nanomachine detects and decodes the transmitted information. The most fundamental propagation channel is the diffusion channel, where particles move without external energy according to the Brownian motion. To overcome the slow propagation of the molecules in the pure diffusion channel a flow can be introduced into the environment. The main driving force for research on MC are biomedical applications such as targeted drug delivery or smart disease detection.

Our research focus lies on the physical layer characterization of MC. Hence, we are currently engaged in the following topics:
  • Design and analysis of appropriate signal modulation techniques for MC, by means of analytical and simulation methods.
  • Investigation of intersymbol interference in MC, which comes from delayed arrival of molecules.
  • Validation of analytical and numerical results using experiments. For example we build a macroscale testbed to gain hands-on experience on MC.
Macroscale Testbed: 1: Channel (pipe), 2: Transmitter (electrical spray), 3: Ventilator, 4: Receiver (sensor).
