This application note reports the performance of BIOPAC hand dynamometers SS25LA and TSD121C at grip forces below 1 kg. These devices are specified to register clench force range 0-50 kgf. Performance was measured using the MP150, MP36/MP36R, and MP45.
An alternative for low grip strength measurements is a Response/Hand Force transducer—SS56L, BN-CLENCH, or TSD114-MRI—which is configured with a high sensitivity pressure transducer. Subjects can squeeze a bulb by hand (or apply pressure via foot, thigh, etc.) to indicate a response. The device can provide reduced hysteresis and improved sensitivity at low levels.
Easily record great ECG data and derived signals for heart rate, RR interval, and R-wave amplitude. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system and reduces noise artifact.

Recent Studies using BIOPACs MP-Series (MP160, MP150) data recorders, ECG Amplifiers, and BioNomadix Wireless recorders: Singing style to infants Mothers around the world sing to infants, presumably to regulate their mood and arousal. Lullabies and playsongs differ stylistically and have distinctive goals. Mothers sing lullabies to soothe and calm infants, and playsongs to engage and […]
Alex Dimov, BIOPAC Sales Executive, was interviewed at the Neuromarketing World Forum by Inside Marketing to discuss how virtual reality can improve marketing research. Alex explains how VR can be used to present virtual iterations of a product to save time and money, and notes that measuring physiological responses adds lots of information for product and messaging […]
