OFET Sensors Titto Thomas 133079015 M.Tech Seminar 2. Introduction Sensors Transducer Conversion into signals Applications [2] Organic conducting polymers Discovery [1] Applications Organic Thin Film Transistor (OTFT) [1] H. Shirakawa et al. , “Synthesis of electrically conducting organic polymers: halogen derivatives of polyacetylene, (ch),”, 1977 [2] P. Lin and F. Yan So I tried using a transistor as a power supply for the sensors, then controlling the transistor with a pin to effectively turn on or off the power to the bank of external devices. Problem is, it didn't work. The transistor got hot and only output a couple volts. I can't figure out why it didn't work, do you know of any reasons why it shouldn't?
2018-03-08 2021-04-01 2019-03-23 TMP36 is specifically a temperature sensor, not an NPN transistor like the 2N2222. You might have them confused because they both can come in TO-92 package. It is possible to look at the various properties of 2N2222 transistor and correlate it to temperature (see the other answers on this page), but that seems not practical for your application. Introduction. Transistors make our electronics world go 'round.

We have identified new DNA aptamers for phenylalanine in two formats, initially as fluorescent sensors and then, incorporated with field-effect transistors (FETs). Aptamer-FET sensors detected phenylalanine over a wide range of concentrations (fM to mM).
