David Gracias and Ishan Barman at Johns Hopkins have developed a COVID 19 sensor which provides fast and accurate results using a drop of saliva placed on a device. No additional chemical modifications like molecular labeling or antibody functionalization are required, which could allow the sensor to be used in wearable devices. Current PCR tests […]

Shallow implant plus precise stimulation startup aims to treat depression
Inner Cosmos is a new, shallowly implanted brain stimulation system meant to address depression. It calls its system a “digital pill” but still requires a procedure for electronics to be placed under the skin on the head. Chief Medical Officer Eric Leuthardt is a top neurosurgeon from Washington University in St Louis and the CEO […]

Zenan Bao further develops stretchable, potentially reshapeable, skin inspired electronics
Stanford’s Zhenan Bao and team have developed a stretchable, potentially reshapeable, wearable display that can allow a new way of interactive human-machine interface. “We can see the image and interact with it, and then the display can change according to our response” said Bao in a Stanford interview. The display is made entirely of stretchy […]

Stanford study: High dose magnetic stimulation eases severe depression
Nolan Williams, Alan Schatzberg, and Stanford colleagues have published a small, double blind study showing that high dose, noninvasive, magnetic brain stimulation alleviated depression symptoms in 80% of participants. Stanford accelerated intelligent neuromodulation therapy (SAINT) is an intensive, individualized form of transcranial magnetic stimulation. Effects were seen within days and lasted months. Side effects included […]

Passive EEG assessment detects cognitive decline early
George Sothart and University of Bath colleagues have developed a new, EEG + game memory assessment technique which could enable the earlier diagnosis of Alzheimer’s disease, the underlying cause of around 60% of dementia cases.. The need for early diagnosis tools to help doctors to prescribe lifestyle interventions to slow the rate of cognitive decline […]

Candy sensor prototype to monitor electrolytes, ovulation, kidney function through saliva
Korea University professors Beelee Chua and Donghyun Lee have developed a health monitoring sensor using saliva collected from a Tootsie Roll candy to detects salt and electrolyte levels, and monitor ovulation status and kidney health. The easily accessible, low-waste sensor is simply licked. To make the prototype sensor, a Tootsie roll was flattened and crevices […]
