Caretaker Prime Minister Thaksin Shinawatra once wore a popular yellow wristband. Now he has a new accessory.

For the past three weeks, he has been wearing a black Philip Stein bracelet on his left wrist.

The Matichon newspaper reported that Piyapat Voravanit, a son-in-law of Thai Rak Thai Party deputy leader Prayudh Mahagitsiri, gave Thaksin the bracelet. It was understood to have cost Bt30,000. Thaksin's son Panthongtae has been seen wearing one, too.

Checking out its qualities, it is clear why Thaksin decided to wear the bracelet. Amid the current political uncertainty,  he might need something to reduce stress.

The accessory is implanted with a "Teslar" chip.

According to the Philip Stein website, Teslar technology was "designed to emit a unique signal that strengthens the body's own natural electromagnetic energy field and helps the body better resist potentially negative effects of external, low-energy electromagnetic fields given off by cellular telephone systems, computers and other electronic devices".

As a result of the "Teslar effect", wearers experienced "deeper, more restful sleep, more calm and less tension, improved concentration, increased levels of energy and an over-all improvement in well-being".

To make the bracelet work effectively, wearers must wear it on their left wrist, the same side as the heart.
