Thin film thermoelectric energy harvesters for MEMS micropower generation
Topal, Emre Tan; Külah, Haluk; Muhtaroglu, Ali (2010-12-01)
In this study, we propose a novel thin film thermoelectric energy harvester design based on Cr-Ni thermocouples overlayed on top of a suspended parylene diaphragm. The TE energy harvester can be used to harvest excess heat energy generated at the hot spots in a computer platform. The design can be merged with the previously reported EM energy harvester within a MEMS device to scavenge energy from both vibrations and thermals in a hybrid mode of operation. The performance evaluation of the MEMS integrated th...
Thin film piezoelectric acoustic transducer for fully implantable cochlear implants
Ilık, Bedirhan; Koyuncuoglu, Aziz; Sardan-Sukas, Ozlem; Külah, Haluk (Elsevier BV, 2018-09-01)
This paper reports the development of a single cantilever thin film PLD-PZT transducer prototype. The device was experimentally characterized by attaching it on an acoustically vibrating membrane resembling the behavior of the eardrum. Acceleration characteristic of the sensor attached on the membrane was obtained by using a Laser Doppler Vibrometer (LDV) as the output voltage was measured by an oscilloscope. A voltage output of 114 mV was obtained, when the device was excited at 110 dB Sound Pressure Level...

This paper presents design and fabrication of a MEMS-based thin film piezoelectric transducer to be placed on an eardrum for fully-implantable cochlear implant (FICI) applications. Resonating at a specific frequency within the hearing band, the transducer senses eardrum vibration and generates the required voltage output for the stimulating circuitry. Moreover, high sensitivity of the sensor, 391.9 mV/Pa @900 Hz, decreases the required power for neural stimulation. The transducer provides highest voltage ou...
