“…However we use commercially available parts which allows for easy scaling of the electronics fabrication and our process for gluing the electronics to the insects is similar to the process for attaching tracking markers to bees in commercial hives. Additionally, researchers have also shown that insects can survive common microfabrication processes such as deposition of conductive material in a vacuum chamber [68,69] and performing surgeries at different stages of an insect's life cycle. This suggests potential approaches for mass attachment of electronics or fabricating devices on insects themselves.…”

Sensor networks with devices capable of moving could enable applications ranging from precision irrigation to environmental sensing. Using mechanical drones to move sensors, however, severely limits operation time since flight time is limited by the energy density of current battery technology. We explore an alternative, biology-based solution: integrate sensing, computing and communication functionalities onto live flying insects to create a mobile IoT platform.Such an approach takes advantage of these tiny, highly efficient biological insects which are ubiquitous in many outdoor ecosystems, to essentially provide mobility for free. Doing so however requires addressing key technical challenges of power, size, weight and self-localization in order for the insects to perform location-dependent sensing operations as they carry our IoT payload through the environment. We develop and deploy our platform on bumblebees which includes backscatter communication, low-power selflocalization hardware, sensors, and a power source. We show that our platform is capable of sensing, backscattering data at 1 kbps when the insects are back at the hive, and localizing itself up to distances of 80 m from the access points, all within a total weight budget of 102 mg.

Living muscle tissue and cells have been attracted as an actuator candidate. In particular, an insect dorsal vessel (D V) tissue is well suited for an actuator since it is capable of contracting spontaneously and more environmentally robust under culturing conditions compared with mammalian tissue and cells. Here we demonstrate a temperature-tolerant microrobot powered by insect DV tissue. A polypod micro robot was designed and fabricated by assembling a whole DV tissue to an inverted two-row micropillar array consisting of 72 micropillars. Using this microrobot, a contractile force of a whole DV tissue was estimated. The polypod microrobot moved in designed direction successfully at a velocity of 1.3 �m/s. These results indicate that the DV tissue has a high potential for an actuator of a temperature-tolerant micro robot.

“…When kept at 55 mTorr pressure for 60 min more than half of the flies survived. 13 As another example, a segment of dorsal vessel (DV) tissue of a cockroach embryo continued to contract for more than 260 days in culture medium. 14 Due to their robustness not only at an individual level but also at a tissue level, insects could be useful as a biological part of a hybrid robot system.…”

We present a bioactuator powered by insect dorsal vessel tissue which can work for a long time at room temperature without maintenance. Previously reported bioactuators which exploit contracting ability of mammalian heart muscle cell have required precise environmental control to keep the cell alive and contracting. To overcome this problem, we propose a bioactuator using dorsal vessel tissue. The insect tissue which can grow at room temperature is generally robust over a range of culture conditions compared to mammalian tissues and cells. First, we confirm that a dorsal vessel tissue of lepidoptera larva Ctenoplusia agnata contracts spontaneously for at least 30 days without medium replacement at 25 degrees C. Using the dorsal vessel tissue cultured under the same conditions, we succeed in driving micropillars 100 microm in diameter and 1000 microm in height for more than 90 days. The strongest displacement of the micropillar top occurs on the 42(nd) day and is 23 microm. Based on these results, the contracting force is roughly estimated as 4.7 microN which is larger than that by a few mammalian cardiomyocytes (3.4 microN). Definite displacements of more than 10 microm are observed for 58 days from the 15(th) to the 72(nd) days. The number of life cycles can be roughly calculated as 7.5 x 10(5) times for the average frequency of about 0.15 Hz, which is no less than that of conventional mechanical actuators. These results suggest that the insect dorsal vessel tissue is a more promising material for bioactuators used at room temperature than other biological cell-based materials.
