  biobatteries are emerging energy storage devices which stimulate nature b
 iochemical reaction in human body to convert chemical energy into electric
 ity by using biocatalyst enzymes in safe way. An important goal of the bio
 battery study is to realize an implantable application. In order to achiev
 e it\, minimizing the biobattery to make implantable application possible 
 is a key step. In previous research\, we have realized a long biobattery d
 ischarge with stable power Output of more than 450 h in phosphate buffered
  saline and 170 h in human serum as big device. The biggest challenge in p
 resent work is to gain high power output and continuous discharge. The pow
 er density reduces a lot in micro size because of reduced reaction surface
  and limited immobilization. In this seminar\, I will present our new rese
 arch enzymatic microbiobattery on chip with multi reaction pool (see Figur
 e 1). The micro reaction pool of battery could better immobilize more enzy
 me in the electrode and extend the reaction surface when compared to 2D pl
 anar electrode. Furthermore\, the lattice on the electrode could increase 
 electrons transfer surface to enhance power output. Beneficial from the ad
 vantages of this structure\, for the first time\, the new battery reached 
 a continuous long discharge time more than 1500s in the human serum as a m
 icro enzymatic biobattery.  This device could not only be used as an energ
 y resource\, but also work as a micromotor to supply electricity at the sa
 me time if it is rolled up and immobilize the hole enzyme system of glucos
 e metabolisms.
