A Compact Design for Wireless Powered Resistive Senor

COMPACT DESIGN FOR WIRELESS POWERED RESISTIVE SENSORS

 

VALUE PROPOSITION

Wireless sensors are used to measure different parameters that could not previously be measured. Many wireless sensors on the market today use inductance to measure parameters but there are limited measures that can be done using inductance. Resistive measurements rely on a resistive circuit to measure temperature, currently accurate core temperatures can only be taken from the nose, bladder or rectum, all methods provide discomfort and room for error. MSU researchers have developed a simple cost-effective sensor to measure patient parameters with minimal invasiveness, is accurate and is applicable across many fields.

 

DESCRIPTION OF TECHNOLOGY

The invention uses a resistance loop including a thermistor to measure the temperature, alterations in the resistors allow this device to be applied to other parameters such as pH, pressure and more. The resistance changes as the measurements change, the resistance change is converted to frequency and measured by an exterior antenna making the device wireless and allows for ease of measuring. The sensor can wirelessly transmit accurate data, the device is portable and comfortable for patients, as well as being low cost because it relies only on two to three small circuits. The Resistive sensor is ideal for taking core temperatures with ease as well as applying it across many fields and measurements.
