Implantable Medical Electronics

Vinod Kumar Khanna received the Ph.D. in physics from Kurukshetra University, Kurukshetra (Haryana), India, in 1988. He is an independent researcher from Chandigarh, India, a retired Chief Scientist from the Council of Scientific and Industrial Research (CSIR)—Central Electronics Engineering Research Institute (CEERI), Pilani, India, and a retired Professor from the Academy of Scientific and Innovative Research (AcSIR), Ghaziabad, India. He is a former Emeritus Scientist at CSIR and a Professor Emeritus at AcSIR, India. His broad research areas include designing, fabricating, and characterizing power semiconductor devices and micro- and nanosensors. During his tenure of more than 37 years at CSIR-CEERI, he worked on various research and development projects on thin-film aluminum oxide humidity sensor, power semiconductor devices (high-current and high-voltage rectifier, high-voltage TV deflection transistor, power Darlington transistor, fast switching thyristor, power DMOSFET and IGBT), PIN diode neutron dosimeter, PMOSFET gamma ray dosimeter, ion-sensitive field-effect transistor, microheater-embedded gas sensor, capacitive MEMS ultrasonic transducer, ZnO piezoelectric film-based MEMS acoustic sensor, and other MEMS devices. He is a fellow of the Institution of Electronics & Telecommunication Engineers (IETE), India. He is a life member of the Indian Physics Association (IPA), Semiconductor Society (India), and Indo-French Technical Association (IFTA). He has published 194 research papers in leading peer-reviewed national and international journals and conference proceedings. He has authored 23 books and contributed six chapters to edited books. He has five granted patents to his credit, including two US patents.
