A key challenge in designing a broad range of implant biomedical devices is limited power source. Most of existing biomedical devices rely on batteries with limited lifetime and negative effect on miniaturization potential of the device. To overcome this issue, in this paper we have designed, fabricated and tested a miniaturized flexible device to harvest and convert body generated mechanical energy into electrical energy.
The device works based on the piezoelectric property of a novel nano material, Molybdenum disulfide (MoS2), which is deposited on a flexible substrate. We demonstrated stretching and releasing of deposited single layer of MoS2 in our device can generates power during each pulse of human heartbeat, which can be stored and potentially be used to drive a large set of biomedical devices.
سخنران: دکتر زهرا کوچک
Research Assistant at Stanford University
Zahra Koochak received her BSc and MSc in Electrical Engineering from K.N.T University in 2007 and 2011 respectively. She joined University of California Santa Cruz to do one year research in bio photonics in 2012. Her research there was focused on improving glucose detection by Surface-enhanced Raman spectroscopy (SERS). In 2013, she joined Stanford University to start her PhD program in electrical engineering. Zahra's research area at Stanford is on bio medical implanted devices.
