Trehalose biofuel cells using insect hemolymph for insect robots

Abstract

This paper repots a demonstration of an IC driving by a trehalose biofuel cell (BFC) mounted on insects. First, we evaluated a trehalose oxidized anode. Then, we fabricated an insect-mountable BFC (imBFC) and the maximum power density of 42.9 μW/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> was obtained from the imBFC. Finally, we demonstrated to flash a LED by the imBFC. These results showed the possibility for developing a power source integrated with insects for insect cyborgs.
