temperature sensor

Temperature sensor is an sensing element that is majorly used to find the temperature of any system, similarly the sensor that is used to find the human body temperature are called as thermometric sensor.

resistance temperature detector RTD element consists of lengthy fine

wire wrapped over ceramic core. RTD wire is made of a pure material of metal, so it can show the even minor deflection of the temperature in a system. With RTD until 600’c could be measured accurately. Materials used in RTD are platinum, nickel, copper.

pressure sensor Pressure sensor is a transducer,

that converts signal pulse of body per second into electrical impulse with help of pressure MEMS sensors. This sensor is interfaced with the spygmo-manometer, where pressure is detected and with help of pressure MEMS analog pressure signals are converted electrically.

Bgm sensor BGM: Blood Glucose Monitoring sensor It is a way of testing a

concentrated blood sugar level (glycemia), to diagnose the diabetes mellitus of human body, where the sensing device has the chemically active disposable test stripe. With the help of glucose in blood the blood sugar level is determined

Bio sensors The term bio sensor is a sort of

biological sensor that are made of transducer and biological element.

The analyte interacts with the biological element to get the biological response and later it is converted into electrical response

Types of biological element some of the biological element that are

used in biosensor are,Enzyme Anti-bodyBiological tissuesorganelles

Cancer cell detection The cancer cell detection

sensor consist of, biological tissue of normal organ cell, which act as anode and cancer affected cell act as cathode. while on comparing of anode with body cell, anode it repels and if it attracts with the cathode electrical signal will generated and cancer cell is detected.
