The Priya Ring is currently being developed as a personal fertility sensor

Prima-Temp's technology is being developed to provide precise and accurate core body temperature measurements. 

Our products are being tested to detect subtle changes in temperature, and then communicate that data directly to a smartphone.


Coming Soon: Priya

The Science of Chronobiology Leading to Fertility Prediction


Our first product, Priya, is currently in development. Priya is an internal sensor that will identify the subtle temperature changes that occur prior to ovulation. When a woman using Priya is most fertile, Priya will send an alert to her smart phone.


Our Platform Technologies


In the United States alone, 11 million women are trying to conceive at any one time and 50% of those women use products to help them achieve that goal. Accurate continuous core temperature monitoring identifies the subtle changes in body temperature, providing a convenient and precise means of determining the fertile window.

Future Applications

Obesity and Weight Loss

The calories burned during any activity vary from individual to individual and depend on the metabolic rate. A small rise in core temperature can substantially alter metabolic rate. Core body temperature provides personalized, real-time data for more effective weight loss. 

Heat Exhaustion 

An estimated 5 to 10 million people in the United States work in industries where heat stress is a potential health and safety hazard, including firefighters and military personnel. Each year, more than 1,000 people die from heat stroke in the United States. Continuous core temperature monitoring can better detect heat exhaustion and provide early alerts to take action, well before heat exhaustion progresses to heat stroke. 

Sleep Disorders

Recent studies suggest that poor sleep can affect metabolism and weight gain and contribute to mental health conditions such as depression. In addition, the studies infer that poor sleep can impact memory, cognition, day to day performance, and even increase the risk of cancer. A study from Harvard Medical School estimates the costs of undiagnosed sleep apnea to be $65 billion to $165 billion a year, taking into account medical costs, lost productivity, and traffic accidents. Continuous core temperature monitoring provides a much-improved picture of sleep via circadian rhythm, when compared with other sleep tracking systems.

Early Disease Detection

Cancer Chemotherapy Treatment

The disruption of the temperature circadian rhythm has been associated with cancer progression, while its amplification results in cancer inhibition in experimental tumor models. Circadian timing of anti-cancer medications improves treatment tolerability up to fivefold and doubles efficacy.

Sepsis kills an estimated 200,000 Americans every year – more than most cancers, strokes and heart attacks. Sepsis is the most expensive cause of hospitalization in the United States, with an annual cost of more than $24 billion, according to the U.S. Agency for Healthcare Research and Quality. For every hour delay in treatment of sepsis, there is a 7.6% increase in mortality. Continuous temperature monitoring provides critical data that can predict hospital-acquired sepsis in patients several hours before a diagnosis.
