Here’s a fun application we haven’t heard of yet—using BIOPAC to test relationship compatibility! BIOPAC equipment was recently featured on ABC’s The Bachelor. In the episode, a “matchmaking test” was performed between the bachelor and several of his potential female companions to observe physiological changes that occurred while in close, one-on-one contact. BioNomadix wireless transmitters can be […]
Entropy Change in Human Physiological System Researchers at the NASA Human Engineering laboratory recently took a thermodynamic approach to human physiology to make inferences about internal entropic changes in response to cognitive stress. This novel approach utilized Maxwell relations, which are equations derived through mathematical manipulation of thermodynamic variables, to use physiological measures to calculate a […]
Echium Oil vs. Fish Oil Food and Nutrition researchers have recently taken a look at the health benefits of stearidonic acid (SDA), an omega-3 fatty acid. It had been suggested that SDA has comparable effects on human health to those achieved by intake of fish oil. Rats were tested for blood pressure and electrocardiogram changes […]
BIOPAC Systems, Inc. crossed yet another milestone with its solar power—the company has saved more than 615,000 pounds of CO2 emissions by generating 410,000 kilowatt hours (KWH) since installing solar roof tiles in January 2007. Solar power covers 35-50% of the company’s power needs, depending on the season. In addition to solar roof tiles, the company […]
Political scientist Gregg Murray, Ph.D. recently published a post on Psychology Today regarding electrophysiological cues in highly political individuals. In it, he discusses the inherent biases of those identifying with a certain political party, and underlying physical evidence quantified using electrodermal activity. Murray cites a study performed by Petersen, Giessing and Nielsen in which partisan subjects were hooked up […]
BIOPAC Systems, Inc. and iMotions, Inc. have formed a strategic partnership to give commercial, industrial, and academic researchers worldwide the ability to elevate their research by combining BIOPAC’s best-in-class hardware solutions with the leading iMotions Biometric Research Software Platform. BIOPAC provides a full line of system solutions that measure physiology anywhere, anytime and from any subject, while […]
Humans, much like animals, separate themselves into different social hierarchies often associated by some specific sort of status signal. While animals may assign hierarchies strictly through physiological measures, the Biosocial Model states that speech is often the strongest form of status signaling for humans. BIOPAC user Allan Mazur recently was part of the research team […]
In Technology: Photoplethysmography with a Smart Phone Pulse transit time (PTT) recordings are widely used to make inferences about dynamics of vascular walls and blood pressure variations, parameters useful to the diagnosis of several respiratory conditions. Chinese researchers have developed a method for noninvasive photoplethysmograhic imaging (PPGi) using the dual cameras of a common smartphone, […]
Magnets and Blood Pressure Biomedical researchers in China have recently investigated the possibility of using magnets to alter a person’s blood pressure. They constructed a device that applies a weak, rotating magnetic field around the cerebral cortex. The researchers used a BIOPAC MP150 Data Acquisition System to obtain continuous blood pressure data. What they found […]
Fear of Flying Virtual Reality provides a safe environment for treatment of patients with phobias through vivo exposure, although generalization of this type of treatment is rare. Researchers recently used virtual reality equipment to treat a young woman for her fear of flying. They used a BIOPAC VR ultimate system for the patient’s six sessions […]
