This paper presents the first direct-write microfabrication of thin-film thermocouple temperature sensors enabled by controlled manipulation of micro glow plasma. The microplasma is generated at the tip of a micromachined thermocouple alloy electrode at atmospheric pressure, enabling localized sputtering deposition of the alloy on the substrate to create(More)
High-Q factor voltage controlled oscillators (VCO) need a wide tuning range and low phase noise over gigahertz ranges of frequency which depends on the tunability of the capacitors in the LC tank circuit. The reasons behind the development of a micro electro mechanical (MEM) varactor were the difficulties encountered in the realization of on-chip variable(More)
Microelectromechanical systems (MEMS)-based vibratory structures have become popular due to their simple fabrication processes, high quality factors, low loss and high sensitivity. Applications of such devices as sensors require a proper understanding of their operational characteristics in various regimes. This work is a study of the dynamics of an(More)
This paper reports an electromechanical micro circuit breaker device developed for self-temperature regulation and safe operation of electronic implants that produce heat in vivo. A micromachined cantilever actuator made of nitinol is used as a normally closed thermoresponsive switch to prevent the host implant from overheating. The device is packaged to be(More)
A Au/bovine serum albumin (BSA)-ZnO (n-type nanoparticles)/Au system is investigated for its transport properties using electrical (I-V) characterization in conjunction with spectroscopy techniques for cost-effective power-efficient biosensing. Temperature-dependent variation in different conduction mechanisms is observed with Au/ZnO/Au system as reference.(More)
This paper presents the first micro-scale process for local deposition and direct writing of metal films through sputtering of a micromachined target electrode. The deposition process is achieved via a highly confined micro glow plasma generated between the electrode's tip and the substrate at atmospheric pressure. Using cylindrical copper electrodes with(More)
Voltage controlled oscillators (VCO) with high quality (Q) factors require wide tuning ranges and low phase noise performance which depends on the tunability of the capacitors in the LC tank circuit. Microelectromechanical (MEM) varactors are being considered as replacements for VLSI on-chip variable capacitors due to the susceptibility of the latter to(More)
