AiQ develops "smart textiles" for a range of custom apparel, including a vital sign monitoring system in a t-shirt. The BioMan t-shirt has ribbed "smart sleeves" that measure the user's heart rate, respiration rate and skin temperature. The garment can be further customized to measure skin moisture and electrophysiological signals such as EKG, electroencephalography (EEG), or electromyography (EMG). AiQ sells other specialized "smart" jackets and vests. For instance, the SolarMan vest has built-in solar panels capable of recharging the user's electronic devices. The CameraMan jacket has a built-in HD camera in the left breast pocket area, and the ArmorMan pullover has padding that stiffens on contact to protect the wearer.
