Bio-MEMs Agile Sensor Platforms and Communication Networks

This effort proposes the development of "OrthopterNets" -- a novel approach applying mobile ad hoc network (MANET) communications networks for the transfer of intelligent information via insect calls (e.g., cricket calls). Insects will be equipped with embedded MEMS transceivers that pick up modulated calling sounds from nearby insects. Once the information in a call is extracted by the transceiver, the information code is applied to an electromechanical device on board the insect that modulates the insect calls, thereby retransmitting the information to another insect, and so on. The modulation mechanism, among other methods, affects the sound producing movements (stridulation) of an insect''s wings. Human or machine-based detectors would demodulate and extract the transmitted information. Work leverages existing MEMS technologies already deployed in insect species by the team and elsewhere. Phase I will focus on the applicability of certain insect species to OrthopterNets, applicable MEMS devices, and issues related to energy harvesting, environmental factors, development of an OrthopterNet networking protocol, and other tasks. Complementary technologies, such as the use of RF microtransmitters and receivers embedded in the insects will also be investigated.
